To develop novel side-chain liquid crystalline conducting polymers, we have synthesized a series of mono-substituted acetylene, thiophone, and pyrrole derivatives with phenylcyclohexyl and biphenyl groups as a mesogenes with a different alkyl substituent, and then polymerized them through chemical polymerization by using Ziegler-Natta and metathesis catalysts for acetulene derivatives and chemical and/or electrochemical polymerizations for thiophene and pyrrole derivatives. Measurements of DSC and polarized microscope for poly(mono-substituted acetylene)s showed that the polymers have smectic liquid crystalline phase, while the monomer with phenylcyclohexyl moiety linked with octyl terminal group has nematic phase. Spectroscopic characterizations were made as well as evaluation of molecular weight and electrical conductivity upon iodine doping. Chemical polymerization of thiophene derivative and electrochemical polymerization of pyrrole derivatives yielded insoluble polymers.

为了开发新型侧链液晶导电聚合物，我们合成了一系列以苯基环己基和联苯基作为具有不同烷基取代基的介晶的单取代乙炔、硫酮和吡咯衍生物，然后使用齐格勒-纳塔和复分解催化剂将它们通过化学聚合进行聚合。 乙炔衍生物以及噻吩和吡咯衍生物的化学和/或电化学聚合。 DSC和偏光显微镜对聚单取代乙炔的测量表明，该聚合物具有近晶液晶相，而带有辛基末端基团的苯基环己基单体具有向列相。进行了光谱表征，并评估了碘掺杂后的分子量和电导率。噻吩衍生物的化学聚合和吡咯衍生物的电化学聚合产生不溶性聚合物。
