Scientific journal, ABSTRACT
Fullerenes attract much interest due to the potentials to various applications. However, their insolubility in water and some organic solvents often hinders development. Herein, poly(ethylene glycol) (PEG), polyvinylpyrrolidone (PVP), poly(vinyl alcohol) (PVA), polyacrylic acid (PAA), and Pluronic L64 and 17R4, are attempted for dispersing fullerene in water via ultrasonication, and some of these are found to disperse an exceedingly large amount. The maximum concentration of C 60 is achieved with Pluronic L64, being 9.8 g/L (13.6 m m ) without re‐aggregation for a long time. Electron paramagnetic resonance (EPR) spectroscopy shows a significant amount of radical species existing in the fullerene–polymer complexes, which are stable for several weeks. DLS and TEM exhibit the formation of nanoparticles, and NMR, FT‐IR, and MALDI‐TOF MS are used to characterize the fullerene nanoparticles–polymer complexes. The aqueous dispersions of the complexes can be dried and redispersed in water and polar organic solvents. Column chromatographic separation is performed to give unreacted fullerene and fullerene–polymer complexes, the latter of which shows a strong EPR signal. Density functional simulations reveal partial electron transfer from the PEG segment to fullerene, which causes charge separation in the complexes, resulting in the excellent dispersibility in water, while the poly(propylene glycol) (PPG) segment likely assists the complexation by hydrophobic interactions with fullerene. - Mildly Catalyzed Alternating Copolymerization Yields Solution-Processable Fluorinated Polyesters with High Thermal and Surface Performance

Scientific journal, Abstract
Tetraalkylammonium salt was found to be an effective catalyst for the ring-opening polymerization of cyclic carbonates and cyclic esters, yielding aliphatic polycarbonates and polyesters with narrow dispersities. An important feature of this catalytic system is its tunable catalytic ability, which was achieved by altering the alkyl substrates and counter anions. The catalytic mechanism was studied by 1H NMR spectroscopy. - Improving the current stability of perovskite quantum dot phototransistors utilizing the ferrocene–cyclodextrin host–guest supramolecules as a floating gate dielectric

Scientific journal, Polyesters (PEs) are sustainable alternatives for conventional polymers owing to their potential degradability, recyclability, and the wide availability of bio-based monomers for their synthesis. Herein, we used a one-pot, one-step self-switchable polymerization linking the ring-opening alternating copolymerization (ROAC) of epoxides/cyclic anhydrides with the ring-opening polymerization (ROP) of L-lactide (LLA) to synthesize PE-based hot-melt adhesives with a high bio-based content. In the cesium pivalate-catalyzed self-switchable polymerization of glutaric anhydride (GA), butylene oxide (BO), and LLA using a diol initiator, the ROAC of GA and BO proceeded whereas the ROP of LLA simultaneously proceeded very slowly, resulting in a copolyester consisting of poly(GA-alt-BO) and poly(L-lactide) (PLLA) segments with tapered regions, that is, PLLA-tapered block-poly(GA-alt-BO)-tapered block-PLLA (PLLA-tb-poly(GA-alt-BO)-tb-PLLA). Additionally, a series of tapered-block or real-block copolyesters consisting of poly(anhydride-alt-epoxide) (A segment) and PLLA (B segment) with AB-, BAB-, (AB)3-, and (AB)4-type architectures of different compositions and molecular weights were synthesized by varying the monomer combinations, alcohol initiators, and initial feed ratios. The lap shear tests of these copolyesters revealed an excellent relationship between the adhesive strength and polymer structural parameters. The (AB)4-type star-block copolyester (poly(GA-alt-BO)-tb-PLLA)4 exhibited the best adhesive strength (6.74 ± 0.64 MPa), comparable to that of commercial products, such as PE-based and poly(vinyl acetate)-based hot-melt adhesives. - Detailed structural analyses and viscoelastic properties of nano-fibrillated bacterial celluloses

Scientific journal, Abstract
mRNA lipid nanoparticles (LNPs) have reached an inflection point and are now paving the way for a new wave of precision therapies. The design of nonhepatocyte RNA delivery systems without targeting ligands, however, remains a challenge. It is reported that the development of ligand‐free glycidylamine (GA) derivatives containing LNPs (GA‐LNPs) that preferentially deliver mRNA to immune cells in the spleen. Notably, it is demonstrated that the stereochemistry of GA‐lipids has a significant impact on their self‐assembly and in vitro and in vivo RNA delivery efficiency and tropism. This impact is dependent on the monomeric structure of GA and number of stereogenic centers. Furthermore, the nonlinear topology of GA lipid derivatives induced a sevenfold improvement in mRNA delivery efficiency. The top‐performing estriol‐GA05‐30 LNPs elicited strong antitumor activity in a therapeutic and prophylactic cancer model and are well tolerated in mice. These results highlight the significance of the chemistry of ionizable lipids for extrahepatic RNA delivery and indicated a promising direction for the development of next‐generation mRNA immunotherapies. - Rotaxane Formation of Multicyclic Polydimethylsiloxane in a Silicone Network: A Step toward Constructing “Macro-Rotaxanes” from High-Molecular-Weight Axle and Wheel Components

Rotaxanes consisting of a high‐molecular‐weight axle and wheel components (macro‐rotaxanes) have high structural freedom, and are attractive for soft‐material applications. However, their synthesis remains underexplored. Here, we investigated macro‐rotaxane formation by the topological trapping of multicyclic polydimethylsiloxanes (mc‐PDMSs) in silicone networks. mc‐PDMS with different numbers of cyclic units and ring sizes was synthesized by cyclopolymerization of a α,ω‐norbornenyl‐functionalized PDMS. Silicone networks were prepared in the presence of 10–60 wt % mc‐PDMS, and the trapping efficiency of mc‐PDMS was determined. In contrast to monocyclic PDMS, mc‐PDMSs with more cyclic units and larger ring sizes can be quantitatively trapped in the network as macro‐rotaxanes. The damping performance of a 60 wt % mc‐PDMS‐blended silicone network was evaluated, revealing a higher tan δ value than the bare PDMS network. Thus, macro‐rotaxanes are promising as non‐leaching additives for network polymers. - Biosynthesis of High-Molecular-Weight Poly(

Scientific journal, The redox behaviors of macrocyclic molecules with an entirely π-conjugated system are of interest due to their unique optical, electronic, and magnetic properties. In this study, defect-free cyclic P3HT with a degree of polymerization (DPn) from 14 to 43 was synthesized based on our previously established method, and its unique redox behaviors arising from the cyclic topology were investigated. Cyclic voltammetry (CV) showed that the HOMO level of cyclic P3HT decreases from –4.86 eV (14 mer) to –4.89 eV (43 mer), in contrast to the linear counterparts increasing from –4.94 eV (14 mer) to –4.91 eV (43 mer). During the CV measurement, linear P3HT suffered from electro-oxidation at the chain ends, while cyclic P3HT was stable. ESR and UV–Vis–NIR spectroscopy suggested that cyclic P3HT has stronger dicationic properties due to the interactions between the polarons. On the other hand, linear P3HT showed characteristics of polaron pairs with multiple isolated polarons. Moreover, the dicationic properties of cyclic P3HT were more pronounced for the smaller macrocycles. - Sequential Polymerization from Complex Monomer Mixtures: Access to Multiblock Copolymers with Adjustable Sequence, Topology, and Gradient Strength

Scientific journal,Abstract Switchable polymerization holds considerable potential for the synthesis of highly sequence-controlled multiblock. To date, this method has been limited to three-component systems, which enables the straightforward synthesis of multiblock polymers with less than five blocks. Herein, we report a self-switchable polymerization enabled by simple alkali metal carboxylate catalysts that directly polymerize six-component mixtures into multiblock polymers consisting of up to 11 blocks. Without an external trigger, the catalyst polymerization spontaneously connects five catalytic cycles in an orderly manner, involving four anhydride/epoxide ring-opening copolymerizations and one L-lactide ring-opening polymerization, creating a one-step synthetic pathway. Following this autotandem catalysis, reasonable combinations of different catalytic cycles allow the direct preparation of diverse, sequence-controlled, multiblock copolymers even containing various hyperbranched architectures. This method shows considerable promise in the synthesis of sequentially and architecturally complex polymers, with high monomer sequence control that provides the potential for designing materials. - Polyether/Polythioether Synthesis via Ring-Opening Polymerization of Epoxides and Episulfides Catalyzed by Alkali Metal Carboxylates

Scientific journal, Silver nanoparticles (AgNPs) are used in a wide range of applications, and the size control and stability of the nanoparticles are crucial aspects in their applications. In the present study, cyclized poly(ethylene glycol) (c-PEG) with various molecular weights, along with linear PEG with hydroxy chain ends (HO–PEG–OH) and methoxy chain ends (MeO–PEG–OMe) were applied for the Tollens’ synthesis of AgNPs. The particle size was significantly affected by the topology and end groups of PEG. For example, the size determined by TEM was 40 ± 7 nm for HO–PEG5k–OH, 21 ± 4 nm for c-PEG5k, and 48 ± 9 nm for MeO–PEG5k–OMe when the molar ratio of PEG to AgNO3 (ω) was 44. The stability of AgNPs was also drastically improved by cyclization; the relative UV–Vis absorption intensity (A/A0 × 100%) at λmax to determine the proportion of persisting AgNPs in an aqueous NaCl solution (37.5 mM) was 58% for HO–PEG5k–OH, 80% for c-PEG5k, and 40% for MeO–PEG5k–OMe, despite the fact that AgNPs with c-PEG5k were much smaller than those with HO–PEG5k–OH and MeO–PEG5k–OMe. - Multidimensional Control of Repeating Unit/Sequence/Topology for One-Step Synthesis of Block Polymers from Monomer Mixtures

Scientific journal, Block copolymers (BCPs) have garnered considerable interest due to their ability to form microphase-separated structures suitable for nanofabrication. For these applications, it is critical to achieve both sufficient etch selectivity and a small domain size. To meet both requirements concurrently, we propose the use of oligosaccharide and oligodimethylsiloxane as hydrophilic and etch-resistant hydrophobic inorganic blocks, respectively, to build up a novel BCP system, i.e., carbohydrate-inorganic hybrid BCP. The carbohydrate-inorganic hybrid BCPs were synthesized via a click reaction between oligodimethylsiloxane with an azido group at each chain end and propargyl-functionalized maltooligosaccharide (consisting of one, two, and three glucose units). In the bulk state, small-angle X-ray scattering revealed that these BCPs microphase separated into gyroid, asymmetric lamellar, and symmetric lamellar structures with domain-spacing ranging from 5.0 to 5.9 nm depending on the volume fraction. Additionally, we investigated microphase-separated structures in the thin film state and discovered that the BCP with the most asymmetric composition formed an ultrafine and highly oriented gyroid structure as well as in the bulk state. After reactive ion etching, the gyroid thin film was transformed into a nanoporous-structured gyroid SiO2 material, demonstrating the material’s promising potential as nanotemplates. - Topology and Sequence-Dependent Micellization and Phase Separation of Pluronic L35, L64, 10R5, and 17R4: Effects of Cyclization and the Chain Ends

Scientific journal, The topology effects of cyclization on thermal phase transition behaviors were investigated for a series of amphiphilic Pluronic copolymers of both hydrophilic–hydrophobic–hydrophilic and hydrophobic–hydrophilic–hydrophobic block sequences. The dye solubilization measurements revealed the lowered critical micelle temperatures (TCMT) along with the decreased micellization enthalpy (ΔHmic) and entropy (ΔSmic) for the cyclized species. Furthermore, the transmittance and dynamic light scattering (DLS) measurements indicated a block sequence-dependent effect on the clouding phenomena, where a profound decrease in cloud point (Tc) was only found for the copolymers with a hydrophilic–hydrophobic–hydrophilic block sequence. Thus, the effect of cyclization on these critical temperatures was manifested differently depending on its block sequence. Finally, a comparison of the linear hydroxy-terminated, methoxy-terminated, and cyclized species indicated the effect of cyclization to be unique from a simple elimination of the terminal hydrophilic moieties. - Trapping probabilities of multiple rings in end-linked gels

Scientific journal,Abstract Nano-sized metal particles are attracting much interest in industrial and biomedical applications due to the recent progress and development of nanotechnology, and the surface-modifications by appropriate polymers are key techniques to stably express their characteristics. Herein, we applied cyclic poly(ethylene glycol) (c -PEG), having no chemical inhomogeneity, to provide a polymer topology-dependent stabilization for the surface-modification of gold nanoparticles (AuNPs) through physisorption. By simply mixingc -PEG, but not linear counterparts, enables AuNPs to maintain dispersibility through freezing, lyophilization, or heating. Surprisingly,c -PEG endowed AuNPs with even better dispersion stability than thiolated PEG (HS–PEG–OMe). The stronger affinity ofc -PEG was confirmed by DLS, ζ-potential, and FT-IR. Furthermore, thec -PEG system exhibited prolonged blood circulation and enhanced tumor accumulation in mice. Our data suggests thatc -PEG induces physisorption on AuNPs, supplying sufficient stability toward bio-medical applications, and would be an alternative approach to the gold–sulfur chemisorption. - Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructures

Scientific journal,Abstract
Discrete block co-oligomers (BCOs) are gaining considerable attention due to their potential to form highly ordered ultrasmall nanostructures suitable for lithographic templates. However, laborious synthetic routes present a major hurdle to the practical application. Herein, we report a readily available discrete BCO system that is capable of forming various self-assembled nanostructures with ultrasmall periodicity. Click coupling of propargyl-functionalized sugars (containing 1–7 glucose units) and azido-functionalized terpenoids (containing 3, 4, and 9 isoprene units) afforded the discrete and monodisperse BCOs with a desired total degree of polymerization and block ratio. These BCOs microphase separated into lamellar, gyroid, and cylindrical morphologies with the domain spacing (d ) of 4.2–7.5 nm. Considering easy synthesis and rich phase behavior, presented BCO systems could be highly promising for application to diverse ~4-nm nanofabrications. - Programmed folding into spiro-multicyclic polymer topologies from linear and star-shaped chains

English, Scientific journal, A novel strategy for downsizing the feature of microphase-separated structures was developed via the intramolecular crosslinking reaction of block copolymers (BCPs) without changing the molecular weight. A series of BCPs consisting of poly[styrene-st-(p-3-butenyl styrene)] and poly(rac-lactide) (SBS-LA) was subjected to Ru-catalyzed olefin metathesis under highly diluted conditions to produce intramolecularly crosslinked BCPs (SBS(cl)-LAs). Small-angle X-ray scattering measurement and transmission electron microscopy observation of the SBS(cl)-LAs revealed feature size reduction in lamellar (LAM) and hexagonally close-packed cylinder (HEX) structures in the bulk state, which was surely due to the restricted chain dimensions of the intramolecularly crosslinked SBS block. Notably, the degree of size reduction was controllable by varying the crosslink density, with a maximum decrease of 22% in the LAM spacing. In addition, we successfully observed the downsizing of the HEX structure in the thin film state using atomic force microscopy, indicating the applicability of the present methodology to next-generation lithography technology. - Microphase separation of carbohydrate-based star-block copolymers with sub-10 nm periodicity

Chemical science, 10, 2, 440, 446, 14 Jan. 2019, [Peer-reviewed], [International Magazine]
English, Scientific journal, Cage-shaped polymers, or "macromolecular cages", are of great interest as the macromolecular analogues of molecular cages because of their various potential applications in supramolecular chemistry and materials science. However, the systematic synthesis of macromolecular cages remains a great challenge. Herein, we describe a robust and versatile synthetic strategy for macromolecular cages with defined arm numbers and sizes based on the intramolecular consecutive cyclization of highly reactive norbornene groups attached to each end of the arms of a star-shaped polymer precursor. The cyclizations of three-, four-, six-, and eight-armed star-shaped poly(ε-caprolactone)s (PCLs) bearing a norbornenyl group at each arm terminus were effected with Grubbs' third generation catalyst at high dilution. 1H NMR, SEC, and MALDI-TOF MS analyses revealed that the reaction proceeded to produce the desired macromolecular cages with sufficient purity. The molecular sizes of the macromolecular cages were controlled by simply changing the molecular weight of the star-shaped polymer precursors. Systematic investigation of the structure-property relationships confirmed that the macromolecular cages adopt a much more compact conformation, in both the solution and bulk states, as compared to their linear and star-shaped counterparts. This synthetic approach marks a significant advance in the synthesis of complex macromolecular architectures and provides a platform for novel applications using cage-shaped molecules with polymer frameworks. - A Comparative Study of Dynamic Light and X-ray Scatterings on Micelles of Topological Polymer Amphiphiles

Trans-1,4-Polybutadiene (TPBD) transforms a crystal structure at the temperature of heat storage. In this study, the molecular structure of TPBD was measured using the Raman spectroscopy. The measurement of the amount of heat storage of TPBD was performed using a differential scanning calorimetry. It is found that there is a correlation between the amount of heat storage and the change of C-H bond by auto-oxidation. A thermal cycle test was carried out to obtain the change of heat storage and release amount of TPBD. The heat storage and release amount was calculated from the obtained temperature history. The heat storage amount became between 60 J/g and 90 J/g. The heat release amount became between -70 J/g and -100 J/g. It is verified that the amount of heat storage of TPBD does not deteriorate during 1700 cycles., JAPAN SOCIETY OF THERMOPHYSICAL PROPERTIES, Japanese - Sub-20 nm microphase-separated structures in hybrid block copolymers consisting of polycaprolactone and maltoheptaose

本研究は、日仏台の3か国共同体制によって、糖鎖をバイオベース原料ならびに機能発現部位として活用することで、高強度・高靭性バイオベース高分子材料を創出することを目的としている。今年度は下記の3点について重点的に検討を進めた。
①糖鎖ブロックの合成検討:バイオベース高分子の根幹となる糖鎖ブロックの合成検討を行った。糖鎖としてセルロースを選択し、酵素合成法によって還元末端に反応性基(プロパルギル基)を導入した低分子量セルロースを精密合成した。材料物性と生分解性の両立を目指し、得られた末端官能基化セルロースを様々なアセチル化条件に付すことで置換度を制御した末端官能基化アセチルセルロースの合成に成功した。
②糖鎖ベースエラストマーの合成:各置換度のアセチルセルロースを両末端アジド化ポリデカノラクトンとクリック反応させることで、ハード-b-ソフト-b-ハード型のトリブロック共重合体を合成した。得られたブロック共重合体は糖鎖とポリデカノラクトン間でミクロ相分離し、置換度の減少とともにより規則的なミクロ相分離構造を形成することを見出した。引張試験を行った結果、柔らかく伸びる性質が確認され、セルロースベースのエラストマー材料の開発に成功した。
③相溶化剤としての応用:また、上記で得た酢酸セルロースを用いることで、ポリカプロラクトンと酢酸セルロースからなるブロック共重合体を合成した。これを酢酸セルロースとポリカプロラクトンからなるブレンドに添加すると、柔らかいポリデカノラクトンドメインの相溶化により破断伸びを向上させることに成功した。
以上に加えて、海外共同研究者であるBorsali(フランス)、Chen(台湾)およびChiu(台湾)らそれぞれとオンラインミーティングを開催した。本研究プロジェクトに関する進捗状況や今後の研究方針、来年度以降の渡航スケジュールなどについてオンラインで議論を行った。

In this study, structurally and physicochemically diverse amino-functionalized polyesters (APEs) were precisely synthesized, aiming to create nanocarriers capable of selectively delivering nucleic acids to various major organs through screening of APE-based polymer-lipid hybrid nanoparticles (PLNPs). Specifically, APEs were synthesized via ring-opening polymerization of caprolactone derivatives using aminoalcohols. A library comprising over 100 variants was constructed by varying initiators, monomers, and degrees of polymerization. Among them, several PLNPs incorporating APE components demonstrated selectivity towards the lungs and spleen. Additionally, the ring-opening alternating copolymerization of glycidylamine and cyclic anhydrides was explored as a method to construct a novel APE library.

Microphase-separated structure formed by block copolymers (BCPs) is promising as a template for constructing nanostructures, and the application in nanofabrication with single-nanometer resolution is highly expected. To achieve precise nanofabrication in such ultrasmall size region, conventional polydisperse BCPs are no longer sufficient, and monodisperse BCPs will become the mainstream in the future. In this study, we aimed to establish molecular design guidelines of monodisperse BCPs for constructing asymmetric lamellar structures and network structures required for engineering applications. We focused on BCPs based on monodisperse oligosaccharides and carried out systematic synthesis. As a result, we succeeded in obtaining asymmetric lamellar and network microphase-separated structures (DG, Fddd, and HPL).

The lattice structure made of carbon fiber-reinforced composite material is a lightweight, high-strength structure that takes full advantage of the stiffness and strength of carbon fiber. However, there are many restrictions on manufacturing lattice structures. In this research, we applied a unique electrodeposition resin impregnation method in which carbon fibers are immersed in an electrodeposition solution used for automobile painting, and a current is applied to deposit and impregnate the fiber surface with resin. (A) We have developed a manufacturing method for the lattice structure. In addition, (B) we demonstrated a method to strengthen the lattice structure by adding cellulose nanofibers, which are sustainable resources and have excellent strength. Furthermore, (C) we progressed with the development of a method to combine heat storage material with resin impregnation at the same time as realizing a lightweight, high-performance CFRP heat sink.

Nanofibrillated bacterial cellulose (NFBC) exhibits shear-shearing flow behavior, in which the viscosity decreases with increasing shear rate even at low concentrations, and its high aspect ratio is confirmed to form a network structure. Various surface modification methods, such as silane coupling and grafting, were investigated to add new functions to NFBC. As for the drug delivery, by supplementing the anticancer drug in the dense network structure, it was possible to suppress the toxicity and efficiently deliver the drug to cancer cells intraperitoneally.

This study aims to establish new methodologies for controlling the periodicity (domain-spacing) of the microphase-separated structure formed by block copolymers (BCP) to about 5 nm. As a methodology to achieve this, in this study, we mainly examined (1) the restriction of the polymer chain dimension by introducing intramolecular cross-linking into BCP and (2) the introduction of macrocyclic units into BCP. As a result, in the methodology (1), the introduction of intramolecular cross-linking succeeded in reducing the domain-spacing by up to 47%, and in the methodology (2), the domain-spacing was reduced by up to 76% as compared with the corresponding linear BCP.

Cage-shaped nanoobjects which composed of synthetic soft polymer framework was successfully synthesized and subjected to structural analysis. The three-armed cage-shaped polycaprolactone as a model macromolecule was synthesized and characterized by small-angle X-ray scattering experiment in solution state, which revealed that the cage-shaped macromolecule had a unique folded dimension as compared to the linear counterpart. In addition, we have established a cyclopolymerization strategy to graft polymers with densely arrayed cage-shaped PCL side chains. This synthetic method allowed the control of number of cage-shaped units of graft polymers, which enabled systematic characterization. Since all the synthetic method that we used can be applicable to diverse polymer species, the cage-shaped nanoobjects with desired number of cage-shaped units will be easily obtained. The cage-shaped nanoobjects with soft polymeric framework could be new promising candidate for materials application.

Monodisperse block copolymers (BCP) with discrete degree of polymerizations were readily synthesized starting from oligosaccharides and terpenoids. Since the monodisperse oligosaccharide-based BCPs are consisted of a highly immiscible pair of saccharides and hydrocarbons, they successfully microphase separate into well-ordered morphologies despite their low molecular weight of less than 2000 g/mol. Depending on the volume fraction and degree of polymerization, the BCPs formed the lamellar, gyroid, and hexagonally close-packed cylinder microphase-separated morphologies with 4 - 8 nm periodicity. By comparing with the polydisperse version of the BCPs, it was found that the monodispersity is critically important to realize the small periodicity and to reproduce the microphase-separated structures.

Branched and cyclic amphiphilic BCPs as well as tacticity-controlled amphiphilic BCPs were synthesized by using precision polymerization techniques and click reactions. A systematic investigation into those BCPs revealed that the incorporation of branched and cyclic architectures into the BCPs can be an effective mean to reduce the domain-spacing of the microphase-separated structures. Further, the control over the main chain tacticity can be a novel approach to achieve high-quality morphology.

We here proposed a novel synthetic route toward multicyclic polymers based on the consecutive cyclization of linear polymer precursors possessing a polymerizable group at each chain end. Specifically, the consecutive cyclization was achieved by the cyclopolymerization of macromonomers bearing a norbornenyl group at each chain end, affording multicyclic polymers with the targeted ring size and number of cyclic units. Furthermore, we have performed a systematic investigation of the correlation between the multicyclic architecture and physical properties.

Block copolymers (BCPs) carrying olefinic side chains were subjected to the olefin metathesis reaction using Grubbs 2nd generation catalyst under highly diluted condition to produce the intramolecularly cross-linked BCPs. The self-assembly behaviors of the intramolecularly cross-linked products and their parent BCPs were evaluated in terms of micellization in water and microphase separation in the bulk. Importantly, it was found that the size and morphology of the resultant self-assembled nanostructures can be tuned by the degree of cross-linking. This would be very interesting as a new approach to control the self-assembly behaviors without changing the molecular weight and monomer composition of the BCP.

Biodegradable porous film was fabricated using a rod-coil block copolymer consisting of poly(n-hexylisocyanate) (PHIC) and biodegradable polymers as a compatibilizing agent. At first, we prepared polymer alloy films composed of PHIC, biodegradable polymer, and compatibilizing agent. After annealed the film, the film was soaked into hexane to selectively remove PHIC from the film. The prepared film was observed by atomic force microscope (AFM) and confirmed to form pores. The average pore size was about 500 nm and cross sectional analysis showed that the pore persisted from the top surface to the substrate. In addition, biodegradable film having microphase-separated structures with sub-20 nm periodicity was fabricated using block copolymers (BCPs) consisting of maltoheptaose and poly(ε-caprolactone) (PCL).

単分子ポリマーナノパーティクル(SCNP)はその興味深い構造から基礎的な性質の理解と応用の両面から興味が持たれる。しかし、SCNPの合成ならびに物性に関する基礎科学は未開拓な部分が多い。本年度は精密リビング重合を駆使することで、構造明確なSCNPの合成法の確立を目指した。ブチルアクリレートと3-ブデニルアクリレートをグループトランスファー重合により共重合することで、側鎖オレフィンを持つ前駆体ポリマーを得た。側鎖にオレフィンを持つ繰り返しユニットは全体の50%程度とした。各生成ポリマーの分子量分散度は1.1以下の非常に狭い値であった。これをGrubbs第2世代触媒を用い、大希釈条件下、分子内で閉環メタセシス反応を行うことでSCNPの合成を行った。ジクロロメタン中、ポリマー濃度を0.8 g/Lとして反応を行った結果、生成ポリマーのNMRからは末端オレフィン由来シグナルの減少と内部オレフィン由来シグナルの出現が確認された。さらに、サイズ排除クロマトグラフィー測定から、生成ポリマーの見かけの分子量が低下していることが判明した。このことより、SCNPの生成が確認された。SCNPのサイズを制御する方法として、反応溶媒にジクロロメタンとヘキサンの混合溶媒を用いた。貧溶媒であるヘキサンの割合を増加させることで、よりサイズの小さなSCNPを与えることが判明した。しかし、ヘキサンの割合を増加させすぎると分子間架橋を誘発して、構造が明確なSCNPが得られないことも明らかとなった。また、得られたSCNPについてCrabtree錯体による接触水素化反応を行うことで単一の繰り返しユニットからなるSCNPを得ることに成功した。以上の成果は、構造明確なSCNPを得るための方法論として有用と考えられ、SCNPの基礎科学を構築するための礎となるものである。

The synthesis of well-defined multicyclic polymers (figure-eight-shaped and trefoil-shaped homo- and copolymers) was achieved by the combination of living/controlled polymerization and click cyclization. The effect of multicyclic architecture on the micelle properties was also investigated. We have synthesized the well-defined figure-eight-shaped and trefoil-shaped polyethers using the combination of the t-Bu-P4-catalyzed ring-opening polymerization of epoxides and intramolecular click cyclization. The strategy should also be effective for the synthesis of amphiphilic figure-eight-shaped and trefoil-shaped block copolyethers. In order to investigate the aggregation behavior of the amphiphilic block copolyethers, the hydrodynamic diameter and the critical aggregation concentration were determined by dynamic light scattering and fluorescence technique using pyrene, respectively.

本研究課題はポリフェニルアセチレン(PPA)主鎖上に刺激応答性を有するロタキサン構造を備えた新規高分子を合成し、外部刺激によるロタキサン部位のシャトリングの情報をポリマー主鎖のらせん構造(キラリティー)や共役長(色調変化)として効率よく出力させるシステムを構築することを最終目標としている。特に、本研究ではジアセチレンの環化重合によりポリマー主鎖上にロタキサン構造を導入できる点に特徴がある。得られた成果を下記にまとめる。
1. pHに応答するロタキサン構造として、クラウンエーテル/二級アンモニウム塩をモチーフとする繰り返し構造を備えたPPA誘導体の合成を試みた。オリゴエチレングリコールの両末端にフェニルアセチレン残基を有するジアセチレンモノマーを環化重合したところ、主鎖上にクラウン環を備えたポリフェニルアセチレンを与えることを見出した。この知見をもとに、嵩高い末端封鎖基を備えた二級アンモニウム塩存在下にこれらのモノマーの環化重合を行った。その結果、モノマーのエチレングリコール鎖長がロタキサン形成に影響を与えることが示唆され、ヘキサエチレングリコール鎖を有する場合に最も高いロタキサン形成率が達成された。
2. 光に応答するロタキサン構造として環状テトラアミド/フマルアミドをモチーフとした繰り返し構造を備えたPPA誘導体の合成を試みた。4つのアミド基を備えたジアセチレンモノマーを設計し、その重合を行ったが溶媒に不溶なポリマーを与えることが判明した。これはモノマー構造が分子内水素結合によって環化しにくいコンホメーションに固定化されたためと考えられる。したがって、アミド結合の位置を設計しなおすことで環化重合が進行するようになると期待される。
以上の結果より、主鎖上に刺激応答性ロタキサン構造を有するポリフェニルアセチレンの精密合成と機能化に向けた礎を築けたと考えている。
