Abstract

Synthesis and polymerization of silacyclobutanes with mesogenic groups were studied. Polymers (PSB-Meso, Meso = mesogenic group) obtained by platinum complex, such as Pt(COD)Cl 2 , had head-tail regular structure, and showed low glass transition and clearing temperatures. PSB-B (Meso = cyanobiphenyl) and PSB-C (Meso = 4-[4-cyanophenyloxycarbonyl]phenyl) exhibited focal-conic fan textures at room temperature under observation by optical polarization micrograph.
