摘要
A series of new photo-cross-linkable and optically active side-chain liquid-crystalline copolymers, 1a-e, were prepared from the hydrosilylation reactions of poly(methylhydrosiloxanes) with (S)-3-[2-((4-cyano-4'-biphenyloxy)-2-methylethoxy]propene (2) and the nematogenic monomer 4-methoxyphenyl 4-(6-hexenyloxy)cinnamate (3) in the presence of Speier's catalyst (H2PtCl6.6H2O in propan-2-ol). The copolymers were found to exhibit chiral smectic C phases. Photo-cross-linking these copolymers at their mesomorphic state enhances the thermal stability of the mesophase.
