ABSTRACT:
A cholesteric liquid crystal composition includes a) a cholesteric liquid crystal compound or a cholesteric liquid crystal precursor; and b) a compound of formula (I), formula (II) or formula (III):where, n is 1, 2, 3, or 4; m is 1, 2, or 3; R is an acrylate, methacrylate, acrylamide, isocyanate, epoxy, or silane; R1is a (C3–C8) alkylene, (C3–C8) alkenylene, or (C3–C8) alkylyne; R2is a bond, —O—, —C(O)O—, —O(O)C—, —OC(O)O—, —C(O)N—, —CH═N—, —N═CH—, or —NC(O)—; R3is a cycloalkylene, cycloalkenylene, heterocyclylene, arylene, or hetroarylene; R4is a bond, (C1–C8) alkylene, (C2–C8) alkenylene, (C2–C8) alkylyne, carbonyl, —O—, —C(O)O—, —O(O)C—, —OC(O)O—, —C(O)N—, —CH═N—, —N═CH—, or —NC(O)—; R5is a bond, cycloalkylene, cycloalkenylene, hetrocyclylene, arylene, or hetroarylene; R6is hydrogen, cyano, halo, (C1–C8) alkoxy, (C1–C8) alkyl, nitro, amino, carboxy, mercapto, (C1–C4)thioalkyl, COCH3, CF3, OCF3, or SCF3; R7is a (C1–C2) alkylene, (C2) alkenylene, or (C2) alkylyne; R8is is hydrogen, halo, (C1–C8) alkoxy, (C1–C8) alkyl, nitro, amino, carboxy, mercapto, (C1–C4)thioalkyl, COCH3, CF3, OCF3, or SCF3; R9is a cycloalkylene, cycloalkenylene, heterocyclylene, arylene, or hetroarylene; and R10is a (C1–C8) alkylene, (C2–C8) alkenylene, or (C2–C8) alkylyne.
