Synthesis of photopolymer containing chalconyl and cholesteryl moieties and their LCD applications
Chalconyl 과 Cholesteryl 기를 함유한 광폴리머의 합성 및 LCD 응용
Abstract
Synthesis of a new copoly (M4Ch-ChMA), copoly ((4-methacryloyloxy) chalcone-cholestery methacrylate), with chalconyl and cholesteryl moiety characteristics for photoalignment materials was investigated. Good thermal stabilities of the synthesized copolymers are confirmed by thermogravimetric analysis (TGA) measurement. The pretilt angles of the nematic liquid crystal (NLC) are reduced as UV exposure time is increased on the copolymer surfaces. A pretilt angle of 81
