Photoresponsive Liquid-Crystalline Polymers Containing a Block Mesogenic Side Chain: Systematic Studies on Structural Parameters for Nanophase-Separated Structures
A family of liquid-crystalline polymers (LCPs) containing a block mesogenicsidegroup was synthesized by varying the hydrophilic moiety (oligooxyethylene) ratio. As the oligooxyethylene content increased, the range of the LC phase narrowed or vanished. The polymers were subjected to annealing and exposed on the surface of films, and their morphologies were observed using an atomic force microscope
