Abstract

Abstract: A new side chain liquid crystalline poly[4-(methacryloxy)hexanoloxy-4′-benzyloxy biphenyl] was synthesized. The phase behavior of the monomer and homopolymer was studied. The monomer shows a smectic B phase, while the homopolymer shows a nematic phase. The nonmesogenic nonlinear optical group was introduced to synthesize a series of side chain liquid crystalline copolymers which also show a nematic phase. Owing to the liquid crystallinity of the copolymer has been the orientational stability improved, down the relax of the orientation slowed and the nonlinear optical properties enhanced.

Key words: Side chain liquid crystalline, Copolymer, Nonlinear optical group
