  We investigated the self-assembly behavior of a series of supramolecular rod–comb block copolymer complexes made by the hybridization of rod–coil diblock copolymers of poly (2,5-di(2-ethylhexyloxy)-1,4-phenylene vinylene)-b-poly(2-vinyl pyridine) (PPV-b-P2VPf) with different volume fractions, f, of the P2VP coils and an anionic surfactant, dodecyl benzenesulfonic acid (DBSA), that selectively interacts

  我们研究了由聚（2,5-二（2-乙基己氧基）-1,4-亚苯基亚乙烯基）-的棒-线圈二嵌段共聚物杂交制得的一系列超分子棒-梳状嵌段共聚物配合物的自组装行为。b-聚（2-乙烯基吡啶）（PPV- b -P2VP f）具有不同体积分数f的P2VP线圈和阴离子表面活性剂十二烷基苯磺酸（DBSA），可选择性地与P2VP相互作用形成侧面-链梳齿。所得的杂种在多个长度尺度上显示出分层有序的结构，形成了所谓的结构中结构形态。值得注意的是，对于PPV- b -P2VP 0.56（DBSA）x，随着DBSA与P2VP单体单元的摩尔比（x）的增加，较大的结构从层状相变为断裂的薄片状层，最终变为六方堆积的带状相。此外，同时进行的SAXS和WAXS测量表明，PPV-P2VP 0.56（DBSA）棒梳系统中较大规模结构的有序无序转变温度高于原始PPV-P2VP 0.56聚合物的相关温度。PPV-P2VP 0.56的大规

  segregated system consists of polyisoprene (PI) coil blocks and poly(alkoxyphenylene vinylene) (PPV) rod blocks solubilized with alkoxy side groups. The order to microphase disorder transition (ODT) and nematic isotropic (NI) transition are experimentally investigated to produce a rod−coil block copolymer phase diagram in a system that follows polymeric scaling relationships.

  在弱偏析极限条件下，研究了一系列单分散棒-油嵌段共聚物的自组装。这种不寻常的弱分离系统由聚异戊二烯（PI）线圈嵌段和可溶解烷氧基侧基的聚（烷氧基亚苯基亚乙烯基）（PPV）棒嵌段组成。对微相无序转变（ODT）和向列各向同性（NI）转变的顺序进行了实验研究，以在遵循聚合物比例关系的系统中生成棒-线圈嵌段共聚物相图。小角X射线散射（SAXS），透射电子显微镜（TEM），偏振光学显微镜，去偏振光散射和广角X射线散射（WAXS）用于绘制相图。随着对称二嵌段共聚物的加热，观察到从层状相向列相向各向同性相的一系列转变。NI转变温度随着线圈分数的增加而降低，并且在高线圈分数下，仅观察到各向同性相。相行为与其他组基于Landau展开的弱偏析计算在定性上吻合。透射电子显微镜（TEM）揭示了低温层状相中不寻常的晶粒结构。棒微区的高弯曲能导致薄片具有长的持久性长度和由破裂的薄片限定的晶界。畴间距随温度的变化表明层

  Luminescent semiconducting organic compounds are widely used as active layers in electro-optical devices. Apart from conjugated polymers, monodisperse oligomers also represent attractive materials. The synthesis of stilbenoid oligomers with polymerizable end groups is presented. Oligo(phenylenevinylene)s with terminal vinyl groups 17-19 are prepared in good yields by Horner-Emmons olefinations or by the fleck reaction of the iodo-substituted oligomers 15, 16 with cornpressed ethene. Triethoxysilyl groups can be linked via rigid 1,2-vinylene units to the chromophores 26-30, either in the direct reaction of 14, 24 with silanes 21, 22 or by cross-metathesis of 17-19 with the vinyl silanes 21, 22 using Grubbs catalyst.

  An improved synthetic method to nitroxide end-capped poly(p-phenylenevinylene)s is presented. The nitroxide-functionalized PPVs are extended with a second coillike block by employing them as macroinitiators in a nitroxide-mediated radical polymerization (NMRP) of monomers like styrene, 4-chloromethylstyrene, 4-vinylpyridine, and n-butyl acrylate. The observed thermotropic properties and morphology of films based on the rod-coil diblock copolymers are identified and described. Some of the block copolymers are subsequently subjected to a coupling with C-60 to incorporate electron-accepting properties into these PPV-based diblock copolymers. For this, a statistical copolymer built from styrene and azidomethylstyrene was used as the second coillike block, making it possible to adjust the built-in ratio of C-60. The morphology and thermotropic properties of films prepared with these diblock copolymers are investigated.
• Push-Pull Chromophore with Phenylene and Thiophene as Conjugation Bridge for Electro-Optic Applications

  We designed and synthesized a push-pull type chromophore (PT-TCF) containing phenylene and thiophene ring as a conjugation bridge. Bulky alkyl chain was substituted into the phenylene bridge to minimize the intermolecular interaction among the neighbor molecules and to enhance solubility of the chromophore in solvents and a polymer host. H-1 NMR and (H-1H)-H-1 COSY spectroscopy confirmed that the chromophore was in all trans-ethenyl conformation. The chromophore exhibited fairly high melting point of 188 degrees C. The chromophore was thermally stable up to 220 degrees C in the nitrogen atmosphere. The relatively high melting point and decomposition on-set may be attributable to the rigid bridge component. The chromophore was blended with an optically transparent polymer host to make a thin film and then its macroscopic optical nonlinearities were evaluated. In a preliminary result, the polymer films containing PT-TCF as a concentration of 50 wt% exhibited electro-optic coefficient as large as 22pm/V taken at 1.55 mu m.
