Abstract

A series of novel side chain liquid crystalline polyacrylates with pendent chiral groups was synthesized. Copolymerization of the monomers was carried out and the physical properties of the copolymers were investigated. Two miscible chiral compounds were also synthesized and used as chiral dopants to induce cholesteric liquid crystalline phases of polymers. The optical properties of the induced cholesteric liquid crystalline polymers were investigated by using UV-vis spectrometer. The appearance and the color variation of the polymer films before and after UV irradiation were also investigated.
