摘要：
A series of liquid-crystalline copolymers poly{6-[4-(4-hexyloxy benzoyloxy)phenoxy]hexyl methacrylate}-co-{6-[4-(S-2-methyl-1-butyloxycarbonylphenylazo)phenoxy]hexyl methacrylate} with an azobenzene moiety as photoreactive mesogenic unit were prepared. Their liquid crystalline Properties and photoinduced anisotropy were investigated. The results showed that these polymers exhibited layered smectic phases and showed good photoinduced anisotropy both in the glass states and in the mesophase states. (C) 1999 Elsevier Science Ltd.
