    Small-angle neutron scattering (SANS) was used to examine dilute solutions of a poly(quinoxaline-2,3-diyl) (PQX) with (R)-2-octyloxymethyl side chains in deuterated THF or a mixture of deuterated 1,1,2-TCE and THF (8/2, v/v), in which the PQX adopts pure P- and M-helical structures. The structures of the PQX that were obtained based on the SANS experiments in combination with theoretical calculations suggest that in THF, the chiral side chains of the P-helical PQX are extended, whereas in the 1,1,2-TCE/THF mixture, the side chains of the M-helical PQX are folded. Consequently, P-helical structures should be preferred in good solvents such as THF, which solvate the extended side chains, whereas M-helical structures should be preferred in poor solvents such as 1,1,2-TCE, wherein the side chains adopt shrunken conformations with maximized van der Waals interactions between the side chains. This study thus reveals the first example for fully determined nuanced conformations of the side chains of synthetic polymers in solution based on SANS experiments and theoretical calculations.

    Poly(quinoxaline-2,3-diyl)s bearing (S)-3-octyloxymethyl and n-propoxymethyl side chains show an abnormal sergeants-and-soldiers effect in n-alkane solvents, which allows the development of a series of PQXs that exhibit an extremely sensitive solvent-dependent helix inversion that permits the discrimination of n-alkane solvents that differ by a single methylene group (e.g. n-heptane and n-octane).

    Six semiflexible helical three-arm star poly[5,8-dimethyl-6,7-bis(propoxymethyl)quinoxaline-2,3-diyl] (A3PQ) samples which have different arm lengths ranging in the weight-average molar mass M-W from 1.5 x 10(4) to 2.5 x 10(5) g mol(-1) were synthesized via the living polymerization of the corresponding 1,2-diisocyanobenzene using a trifunctional palladium initiator. The particle scattering function P(q), the z-average mean-square radius of gyration < S-2 >(z), and the intrinsic viscosity [eta] for the A3PQ samples were determined from light and small-angle X-ray scattering and viscosity measurements in tetrahydrofuran at 25 degrees C. The obtained data were compared with modern theories for the wormlike star. The experimental P(q) data were represented by the wormlike star model connected with a universal joint. The other data were comparably explained by the same model.

    1-Methoxy-8-(diphenylphosphino)triptycene (1), featuring high structural rigidity and steric bulkiness around the phosphine functionality, was synthesized as a new chiral monophosphine ligand for transition metal-catalyzed reactions. In the presence of 5-10 mol ppm (i.e., 0.0005-0.001 mol %) Pd(OAc)2 and 1 (2 equiv for Pd), Suzuki-Miyaura cross-coupling reactions of aryl bromides and arylboronic acids proceeded effectively under mild atmospheric conditions to give the corresponding biaryl compounds in a high yield. The single-crystal X-ray analysis of a Pd(II) complex of 1 revealed its coordination structure, in which two homochiral molecules form a dimer, suggesting that triptycene could provide a chiral environment for asymmetric organic transformations. In fact, optically active 1 obtained by optical resolution showed good enantioselectivity in the palladium-catalyzed asymmetric hydrosilylation of styrene, which represents, for the first time, the asymmetric catalytic activity of triptycene-based monophosphine ligands.

    New functions of helical poly(quinoxaline-2,3-diyl)s (PQX) have been developed on the basis of highly efficient, dynamic induction of single-handed helical structure by using various chiral side chains along with incorporation of achiral functional monomer units. The efficiency and direction of the screw-sense induction are significantly dependent on chiral side chains, achiral side chains, solvents, and pressure according to normal and abnormal sergeants-and-soldiers effect. The dynamic nature of the helix induction allows sharp inversion of their helical sense between two solvents such as CHCl3/1,1,2-trichloroethane, THF/t-butyl methyl ether, and even n-octane/cyclooctane. PQXs having functional units are utilized as chirality-switchable chiral catalysts and materials for emission/reflection of circularly polarized light. Chirality-amplifying asymmetric catalyst system is demonstrated on the basis of majority-rule effect on the induction of macromolecular helical structure.

    Random poly(quinoxaline-2,3-diyl) copolymers, containing achiral 5,8-diarylquinoxaline units and chiral units bearing (S)-2-butoxymethyl groups, exhibited circularly polarized luminescence (CPL). The emission color was fully tunable by changing the aryl substituents on the 5,8-diarylquinoxaline units. An energy transfer from the quinoxaline main chain to the 5,8-diarylquinoxaline units was observed. The handedness of the CPL was dependent on the helical chirality of the polymer main chain, which could be switched by changing the solvent from CHCI3 to 1,1,2-trichloroethane or n-octane to cyclooctane, depending on the chiral side chain.

    An asymmetric synthesis of C-3-symmetric triangular macrocycles is reported. 1-Methylsulfonyl-4-(4-vinylphenyl)-1,2,3-triazole undergoes a rhodium(II)-catalyzed cyclotrimerization to establish an enantiopure C-3-symmetric triangular macrocycle motif. This method can be applied to the synthesis of an enantiopure hydrocarbon, which owes its chirality to asymmetric distribution of H/D atoms on the benzene rings.

    Random poly(quinoxaline-2,3-diyl) copolymers, containing chiral (S)-3-octyloxymethyl and achiral propoxymethyl side chain units, experience an abnormal sergeants-and-soldiers effect, that is, they adopt, depending on the chiral monomer mole fraction, either P- or M-helical conformations in anisole (PhOCH3) and benzotrifluoride (PhCF3). In benzene (PhH) and toluene (PhCH3), these copolymers exclusively adopt an M helical conformation, regardless of the chiral monomer mole fraction. For a co-300mer, with a 40% mole fraction of chiral units, the selective induction of an M-helix (>99%) was observed in PhH, while in PhCF3, a P-helical conformation was induced selectively (>99%). This helix inversion of the polymer backbone is thus able to control the chirality of a chiral polymer ligand in aromatic solvents. The incorporation of a small amount of coordinating PPh2 groups into the copolymer resulted in a chiral macromolecular ligand, which allowed the enantioselective synthesis of both enantiomeric products in an asymmetric Suzuki-Miyaura coupling reaction (R-product: 91% ee in PhH; S-product: 95% ee in PhCF3) from a single catalyst.

    Two poly(quinoxaline-2,3-diyl) copolymers bearing miscibility-enhancing 8-chlorooctyloxy and (S)-2-methylbutoxy or n-butoxy side chains were synthesized. After annealing in CHCl3 vapor, a polymer-blend film of these copolymers exhibited selective reflection of right-handed circularly polarized light (CPL) in the visible region. The handedness of the CPL reflected was completely inverted upon annealing of the film in THF vapor. Annealing in n-hexane vapor resulted in the phase separation of the polymer blend, which turned the selective reflection off. This three-way-switchable reflection, that is, reflection of right-handed or left-handed CPL, together with an OFF state, could be observed visually through right- and left-handed CPL filters.

    Circular dichroism (CD) spectroscopy at high pressure (<= 400 MPa) was accomplished by using polycrystalline yttrium aluminum garnet (Y3Al5O12, YAG) as pressure-resistant optical windows. Conformational changes, including main-chain helix inversions of poly(quinoxaline-2,3-diyl) s (PQXs), in organic solvents at high hydrostatic pressure (> 200 MPa) using a newly developed high- pressure CD cell with polycrystalline YAG windows were demonstrated.

    Polymerizations of 1,2-diisocyanobenzenes to afford poly(quinoxaline-2,3-diyl)s were investigated in the presence of various metal salts and their phosphine complexes, whereby especially the stable and easily-accessible [NiCl2(PMe3)(2)] was found to exhibit a high polymerization activity. The end groups of the resulting polymers were determined by mass spectrometry measurements as -P+Me3 and -H, indicative of a nucleophilic attack of PMe3 towards an isocyano group as the initial step of the polymerization. A chiral polymer ligand, prepared by such a [NiCl2(PMe3)(2)]-mediated polymerization, demonstrated high enantioselectivities in palladium-catalyzed asymmetric hydrosilylation reactions, suggesting that the polymeric catalyst adopted a single-handed helical backbone.

    Chiral random poly(quinoxaline-2,3-diyl) polymers of the sergeants-and-soldiers-type (sergeant units bearing (S)-3-octyloxymethyl groups) adopt an M- or P-helical conformation in the presence of achiral units bearing propoxymethyl or butoxy groups (soldier units), respectively. Unusual bidirectional induction of the helical sense can be observed for a copolymer with butoxy soldier units upon changing the mole fraction of the sergeant units. In the presence of 16-20% of sergeant units, the selective induction of a P-helix was observed, while the selective induction of an M-helix was observed for a mole fraction of sergeant units of more than 60%. This phenomenon could be successfully employed to control the helical chirality of copolymers by applying either random or block copolymerization protocols. Random or block copolymerization of sergeant and soldier monomers in a 18:82 ratio resulted in the formation of 250mers with almost absolute P- or M-helical conformation, respectively (>99% ee). Incorporation of a small amount of coordination sites into the random and block copolymers resulted in chiral macromolecular ligands, which allowed the enantioselective synthesis of both enantiomers in the Pd-catalyzed asymmetric hydrosilylation of beta-methylstyrene.

    A highly efficient majority-rules effect of poly(quinoxaline-2,3-diyl)s (PQXs) bearing 2-butoxymethyl chiral side chains at the 6- and 7-positions was established and attributed to large G(h) values (0.22-0.41kJmol(-1)), which are defined as the energy difference between P- and M-helical conformations per chiral unit. A PQX copolymer prepared from a monomer derived from (R)-2-octanol (23%ee) and a monomer bearing a PPh2 group adopted a single-handed helical structure (>99%) and could be used as a highly enantioselective chiral ligand in palladium-catalyzed asymmetric reactions (products formed with up to 94%ee), in which the enantioselectivity could be switched by solvent-dependent inversion of the helical PQX backbone.

    Light and small-angle X-ray scattering and viscosity measurements in tetrahydrofuran at 25 degrees C were made for nine helical poly[5,8-dimethyl-6,7-bis-(propoxymethyl)quinoxaline-2,3-diyl] samples ranging in the weight-average molar mass M-w from 8 X 10(3) g mol(-1) to 6 X 10(5) g mol(-1) to determine the particle scattering function, the radius of gyration, and the intrinsic viscosity as a function of M-w. The dimensional and hydrodynamic properties were consistently explained in terms of the Kratky-Porod wormlike chain. The helix pitch per residue h (or the contour length per residue) and the chain stiffness parameter lambda(-1) (the Kuhn segment length or twice of the persistence length) were estimated to be h = 0.19 nm and lambda(-1) = 43 +/- 3 run. The former parameter corresponds to an internal rotation angle of about 1200 which is substantially the same as the most stable helical structure estimated from the internal rotation potential. The latter one (lambda(-1)) indicates that the poly(quinoxaline-2,3-diyl) has a rigid helical main chain of which the dihedral angle between adjacent monomer units are restricted by steric hindrance.

    Poly(quinoxaline-2,3-diyl)s bearing (S)-2-methylbutyl, n-butyl, and 8-chlorooctyl groups as side chains were synthesized to fabricate dry solid polymer thin films. These films exhibited selective reflection of right-handed circular polarized light (CPL) in the visible region after annealing in CHCl3 vapor at room temperature. The handedness of reflected CPL was inverted to the left after annealing in 1,2-dichloroethane vapor. It was also found that the color of a particular single film along with the handedness of reflected CPL were fully tuned reversibly, upon exposure of the film to the vapor of various mixtures of chloroform and 1,2-dichloroethane in different ratios.

    Poly(quinoxaline-2,3-diyl)s containing (S)-1-(alkoxycarbonyl) ethoxymethyl side chains derived from natural L-lactic acid were synthesized to investigate the induction of single-handed helical chirality of the main chain. In ether solvents, the handedness of the helical chirality of the polymer main chain is crucially dependent on the length of the alkyl chain in the lactate alkoxy groups. A polymer bearing pentyl ester groups showed an effective solvent-dependent helix inversion between 1,2-dimethyxyethane (1,2-DME, M-Helix) and tert-butyl methyl ether (MTBE, P-Helix). A single-handed copolymer bearing both the pentyl lactate moieties and diphenylphosphino groups was prepared to use as a chiral ligand in an asymmetric Suzuki-Miyaura coupling reaction. The chirality of the ligand could be inverted by the choice of solvents (1,2-DME or MTBE) resulting in the production of either R- or S-enantiomers with high enantiomeric excesses.

    Poly(quinoxaline-2,3-diyl) containing (S)-3-octyloxymethyl side chains was synthesized to investigate the induction of a single-handed helical sense to the main chain in various alkane solvents. The polymer showed an efficient solvent dependent helix inversion between n-octane (M-helix) and cyclooctane (P-helix). After a screening of alkane solvents, it was found that linear alkanes having large molecular aspect ratios induced M-helical structure, and branched or cyclic alkanes having small molecular aspect ratios induced P-helical structure. A polymer ligand containing (S)-3-octyloxymethyl side chains and diphenylphosphino pendants also exhibited solvent-dependent helical inversion between n-octane and cyclooctane, leading to the highly enantioselective production of the both enantiomeric product in a palladium-catalyzed asymmetric hydrosilylation reaction of styrene (R-product 94% ee in n-octane and S-product 90% ee in cyclooctane).

    Poly(quinoxaline-2,3-diyl) copolymers bearing various "sergeant" chiral units with common "soldier" achiral units have been synthesized to investigate the efficiency of screw-sense induction and its dependence on the nature of the solvents. Optically active 2-alkoxymethyl side chains located at the 6- and 7-positions of the quinoxaline ring induced a single-handed helical conformation more efficiently than 3-methylpentyl or 2-methylbutoxy chiral side chains. Among the 2-alkoxymethyl side chains, those bearing higher 2-alkoxy groups induced a single-handed screw sense more efficiently. For instance, a monomer unit bearing (R)-2-octyloxymethyl groups stabilized the P-helix by 1.01 kJ/mol, whereas the monomer bearing (S)-2-butoxymethyl groups stabilized the M-helix by 0.59 kJ/mol. The effect of the position of the sergeant units in the polymer main chain on the screw-sense induction was also investigated using copolymers in which the positions of the sergeant units were carefully controlled by their synthesis via living polymerization. Chiral units placed sparsely could induce single-handed helical structure efficiently. Chiral units bearing 2-alkoxymethyl, 3-methylpentyl, and 2-methylbutoxy groups showed solvent-dependent helix inversion in CHCl3 and 1,1,2-trichloroethane. No helix inversion was observed in those solvents with chiral units bearing 2-butoxy or (2-methylbutoxy)methyl side chains. The 40-mer of the (R)-2-octyloxymethyl units showed P-helical structures in THF, t-BuOMe, and c-C5H11OMe, toluene, pyridine, Et3N, 1-BuOH, CHCl3, CH2Cl2, 1,4-dichlorobutane, 1,1,-dichloroethane, and 1,1,1-trichloroethane, whereas M-helical structures were induced in 1-BuCN, 1-PrCN, 1,2-dichloroethane, 1,3-dichloropropane, and 2-BuOH.

    Polyquinoxaline-based helically chiral phosphine ligands PQXphos, bearing chiral side chains, were synthesized via living aromatizing copolymerization of o-diisocyanobenzene monomers. The chiral reaction environment of PQXphos is created on the basis of its single-handed helical structure, leading to high enantioselectivities in palladium-catalyzed asymmetric hydrosilylation of styrenes (up to 98% ee), Suzuki-Miyaura coupling (up to 98% ee), and silaborative C-C cleavage of meso-methylenecyclopropanes (up to 97% ee). While most common organic solvents induce right-handed helix to (R)-PQXphos bearing (R)-2-butoxymethyl side chains, 1,1,2-trichloro-ethane and some solvents induce left-handed helix to it. The inverted, left-handed (R)-PQXphos also showed high enantioselectivities for the production of enantiomers of the products obtained with right-handed (R)-PQXphos. PQXphos formed insoluble polymer complex through coordination to palladium. The insoluble palladium complex of PQXphos was reused 8 times, while keeping catalyst activity and enantioselectivity. In the silaborative desymmetrization of methylene-cyclopropanes, PQXphos showed not only high enantioselectivity, but also high catalyst activity in comparison with the corresponding low-molecular-weight ligand.

    Poly(quinoxaline-2,3-diyl)s having a terminal formyl or boronyl group were prepared by living polymerization of 1,2-diisocyanobenzenes using organopalladium initiators bearing a protected formyl or boronyl group. Poly(quinoxaline-2,3-diyl)s were successfully deracemized by reacting them with small optically active molecules at their terminal formyl or boronyl group, leading to the induction of optically active helical structures. Poly(quinoxaline-2,3-diyl) having terminal formyl groups was converted to one-handed helical polymer, in which the screw-sense excess was 68% (84:16). The helix sense of the boronyl-terminated poly(quinoxaline-2,3-diyl) was reversibly controlled by attaching and removing the chiral group. (C) 2012 Wiley Periodicals, Inc.

    The poly(quinoxaline-2,3-diyl)-based helically chiral phosphine ligands PQXphos exhibited high enantioselectivities up to 97% ee in palladium-catalyzed desymmetrization of meso-1,2-dialkylsubstituted-3-methylenecyclopropanes through silaborative cleavage of the C C bond. The observed enantioselectivities were higher than those obtained with 2-diarylphosphino-1,1'-binaphthyl in our original report. Remarkable rate enhancement was also observed with a series of PQXphos in comparison with the corresponding low-molecular weight ligands.

    Poly(quinoxaline-2,3-diyl)s bearing pyrene pendants exhibited solvent-dependent changes of the fluorescence color (blue and green) and the screw-sense selectivity (left-handed and racemic) in chloroform and 1,1,1-trichloroethane, respectively.

    Single-handed PQXphos, i.e., helical poly(quinoxaline-2,3-diyl)s bearing diarylphosphino pendant groups, served as remarkable chiral ligands in palladium-catalyzed asymmetric hydrosilylation of styrenes and asymmetric biaryl synthesis by Suzuki-Miyaura coupling, affording up to 98 % enantiomeric excess (e.e.) in both reactions. A palladium complex of high-molecular-weight variant (1000mer) of PQXphos could be reused eight times by virtue of the formation of an insoluble polymer complex. PQXphos underwent solvent-dependent inversion of the helical sense, enabling production of either of two enantiomeric products using a single PQXphos.

    Optically active chiral organonickel complexes served as efficient chiral initiators for living aromatizing polymerization of 1,2-diisocyanobenzene derivatives, which afford optically active helical poly(quinoxaline-2,3-diyl)s up to 84% s.e. (screw-sense excess). In comparison with asymmetric polymerization with the corresponding organopalladium initiators, the nickel initiators show a much greater polymerization rate, while the selectivity remains high. The organonickel initiators can be generated in situ from nickel(0) precursors with the corresponding enantiopure (S,S)-2-(4,5-diphenylimidazolin-2-yl)phenyl chloride, leading to the convenient synthesis of highly stereo-controlled poly (quinoxaline-2,3-diyl)s.

    pi p-Conjugated copolymers composed of 9,9-didodecylfluorene and boron quinolate were synthesized by an efficient chelating reaction of quinolinol-based polyfluorene derivative, as a polymeric ligand, with arylborane compounds such as triphenylborane (BPh(3)) or fluorobis(pentafluorophenyl) borane diethyl etherate ((C(6)F(5))BF center dot OEt(2)). The polymeric ligand was prepared from the deprotection reaction of boron tribromide and benzyloxyquinoline-based polyfluorene, which was produced via the efficient Suzuki cross-coupling reaction of 5,7-dibromo-8-benzylquinoline and 9,9-didodecylfluorene-2,7-diboronic acid in the presence of 2-(2',6'-dimethoxybiphenyl)dicyclohexylphosphine (S-Phos) and palladium(II) acetate. Their optical properties were studied by UV-vis absorption and photoluminescence spectroscopies. The absorption and PL spectra of the obtained polymers were red-shifted in comparison with those of the polymeric ligand due to the decrease of the LUMO level by the formation of boron complexes, explained by theoretical calculations of the model compounds using the density-functional theory (DFT) method. The molar extinction coefficients and emission maxima of boron-chelating polymers were analogous values to those of (kappa(2)-(N,O)-5,7-bis(9,9-dihexylfluoren-2-yl)-8-quinolinolate)diphenylborane (BFluorene(2)q). Furthermore, the electron mobilities of the polymers were determined from the space-charge limited current (SCLC) with electron-only device structure of ITO/Ca/polymer/LiF/Al. As a result, the mobilities for the polymers (3.9 or 2.0 x 10(-5) cm(2)V(-1)s(-1)) were reasonably close to the value (7.9 x 10(-5) cm(2)V(-1)s(-1)) calculated from the Alq(3)-fabricated device.

    A novel luminescent compound, bis((E)-2-pyren-1-yl-vinyl)-2,4,6-triisopropylphenylborane (3) was synthesized by hydroboration reaction and was fully characterized. The obtained compound was further investigated by single-crystal X-ray diffraction analysis and DFT calculations. The extended structure tells us their herringbone structures with closely faced pairs of the molecules. Comparing the photoluminescent spectra between solution-state and solid state, the spectrum of the solid state of the compound 3 exhibited dramatically red-shifted fluorescent emission. This change also supports the efficient π-stacking behavior of the compound 3. © 2009 Elsevier B.V. All rights reserved.

    Hydroboration polycondensations of three aromatic dicyano compounds 1, 1,4-dicyanobenzene (1a), 1,3-dicyanobenzene (1b), and 1,4-didodecyloxy-2,5-dicyanobenzene (1c), with N,N,N',N'-tetramethylethylenediamine-bis(monoisopinocampheylborane) (S-IpcBH(2)center dot TMED) were carried out to obtain optically active poly(cyclodiborazane)s (2a, 2b, and 2c) with M s in the range from 2400 to 6800 in 61-76% yields. The hydroboration polycondensation efficiently proceeded through the complete formation of boron-nitrogen four-membered ring. The polymer structures were characterized by (1)H and (11)B NMR, UV-vis, photoluminescence (PL), and CD spectroscopies. Only 2c exhibited intense blue-green light emission from charge-transfer interaction by incorporation of donor and acceptor system into the polymer backbone. The emission behavior of model compounds (A and B), corresponding to polymer units of 2a and 2c, was effectively examined by theoretical calculations using the DFT method. As a result, the intense blue-green emission of 2c was observed by the bathochromic shift to a visible region. All the polymers showed intense CD signals, indicating that they formed chiral boron-nitrogen four-membered ring structure. Further, 3b and 3c were prepared by hydroboration polycondensation of 1b or 1c with R-IpcBH(2)center dot TMED. The specific rotations of 2a, 2b, and 2c showed positive values in contrast to those of 3b and 3c. The Cotton effects of the cyanobenzene moieties in 2a, 2b, and 2c at around 300-350 nm were positive, whereas the Cotton effects of the cyanobenzene moieties in 3b and 3c were negative, as were the specific rotations as well.

    (Chemical Equation Presented) Diarylboron diketonates were successfully prepared by the reaction of 1,3-diketone derivatives and arylboron compounds such as triphenylborane [BPh3] and fluorobis(pentafluorophenyl)borane diethyl etherate [(C6F6)2BF·OEt 2]. The fluorescent emission of their complexes took place depending on the substituent of the arylboron moiety. In particular, a boron 1,3-bis(4-methoxyphenyl)-1,3-diketonate chelated by a strong electron-withdrawing C6F5 group exhibited the most intense fluorescence. © 2008 American Chemical Society.

    A novel green luminescent compound, (κ2-(N,N')-8- acetylaminoquinolate)diphenylborane (1) was synthesized and fully characterized. To incorporate into the polymer main-chain, (κ2-(N,N')-8- acetylaminoquinolate)bis(4-iodophenyl)borane was also synthesized as a monomer. A new class of fluorescent main-chain type organoboron aminoquinolate polymers were prepared by means of the Sonogashira - Hagihara coupling reaction between diyne monomers and the aminoquinoline monomer. The obtained polymers were further investigated by UV-vis absorption and fluorescence spectroscopy. It was revealed that the fluorescent quantum efficiencies of the obtained polymers depended on the π-conjugated linker unit. In addition, an efficient energy transfer was observed and well π-extended linker units played a role in a light harvesting antenna for the organoboron aminoquinolate units. © 2008 American Chemical Society.

    A main-chain-type organoboron quinolate polymer was prepared by means of polymer reaction between the precursor polymer and triphenylborane. The precursor polymer was synthesized by the Sonogashira-Hagihara coupling reaction between diyne monomer and tert-butoxycarbonyl- (Boc-) protected dibromoquinolinol monomer. The polymer reactions we carried out were successfully achieved and the structures of the obtained polymers were confirmed by IR, 1H NMR, and elemental analyses. The precursor polymers showed blue or green emissions. In contrast, the organoboron quinolate polymer exhibited dramatically red-shifted orange photoluminescence. The quantum yield of the organoboron quinolate polymer was not significantly high. However, the molar extinction coefficient of the polymer at the excitation wavelength was remarkably improved by incorporation of the quinolate structure into the conjugated polymer main-chain. It was suggested that the conjugated main-chain behaved as a light harvesting antenna for organoboron quinolate units. © 2008 American Chemical Society.

    A novel class of rod-coil type-organoboron polymers with p-phenylene-ethynylene as the rod segment and long alkyl chain (decyl group) as coil segment has been prepared from a Sonogashira-Hagihara coupling reaction of a BODIPY-based monomer having bis-iodophenyl and decyl groups with diyne monomers, 1,4-diethynylbenzene (a), 1,4-diethynyl-2,5bis(trifluoromethyl)benzene (b), and 2,7-diethynyl-9,9-dihexyl-9H-fluorene (c). The characterization by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the strong tendency of the obtained polymers, 2a, 2b, and 2c, to self-assemble into particles in solution and as-casted films on a mu m-nm scale. Especially, 2a showed the presence of nm-sized particles and mu m-sized fiber-like structures formed by aggregation of each particle. Further, in CHCl3, the gelation of 2a by three-dimensional aggregation of each fiber was observed at room temperature after 24 h. Their luminescent properties showed high energy transfer efficiency from pi-conjugated polymer linkers to BODIPY moieties (Phi(F) > 71%).

    trans-1,4-Diphosphacyclohexanes were successfully synthesized by the stereospecific intramolecular coupling reaction of the optically active bisphosphine. This is a new route for the construction of the trans-1,4-diphosphacyclohexane skeleton. A cis isomer was also prepared along with the trans isomer from a mixture of rac- and meso-bisphosphines. The coordinated boranes were easily removed to afford the corresponding 1,4-diphosphacyclohexanes.

    The synthesis and properties of conjugated polymers containing organoboron quinolate in their main chain was analyzed. The boron center in monomer B(4-iodophenyl)2q have been determined by single-crystal X-ray diffraction analysis that displays a typical tetrahedral geometry. The hydroxyquinoline groups in all four molecules are chelated to boron to form a five-membered chelate ring. Coupling reactions utilizing Pd and Cu catalysts between B(4-iodophenyl)2q and diyne monomers gave the corresponding polymers. The resulting polymers were dissolved in chloroform and transferred into a separatory funnel and then washed three times with water to remove salts and catalysts. The desired polymers were purified by reprecipitation from diethyl ether. The structures of all products were supported by NMR and elemental analysis. The results of elemental analysis were reasonable with containing iodophenyl groups.

    The first example of well-characterized main-chain type organoaluminum polymers was synthesized by polyaddition between dicyanobenzene derivatives and diisopropylaluminum hydride (DIBAL-H). As dicyano compounds, telephthalonitrile (1a), 1,4-didodecyloxy-2,5-dicyanobenzene (1b), 2,5-dicyanothiophene (1c), 4,4′-dicyanobiphenyl (1d), and 9,9-didodecyl-2,7-dicyanofluorene (1e) were used in the present hydroalumination polymerization. Among these compounds, 1b gave a comparatively stable polymer 2b. The molecular weight of 2b was estimated to be 2800 from gel permeation chromatography measurement. Because of its remaining instability for air and moisture, this molecular weight should be underestimated. The structures of the obtained polymers were confirmed by comparison with spectroscopic data of the model compound in < sup> 1< /sup> H and < sup> 13< /sup> C NMR.

    Novel organoboron polymers containing pyrazabole and electron withdrawing moiety in the main chain were prepared by Heck-Sonogashira coupling. The coupling reaction between various diyne monomers and pyrazabole derivatives gave the corresponding polymers in good yields.

The relation between the electron density on the boron atoms and the optical properties of the corresponding polymers was also studied. © Springer-Verlag 2004.
