摘要：
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; R1 is a (C3-C8) alkylene, (C3-C8) alkenylene, or (C3-C8) alkylyne; R2 is a bond, -O-, -C(O)O-, -O(O)C-, -OC(O)O-, -C(O)N-, -CH=N-, -N=CH-, or -NC(O)-; R3 is a cycloalkylene, cycloalkenylene, heterocyclylene, arylene, or hetroarylene; R4 is 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)-; R5 is a bond, cycloalkylene, cycloalkenylene, hetrocyclylene, arylene, or hetroarylene; R6 is hydrogen, cyano, halo, (C1-C8) alkoxy, (C1-C8) alkyl, nitro, amino, carboxy, mercapto, (C1-C4)thioalkyl, COCH3, CF3, OCF3, or SCF3; R7 is a (C1-C2) alkylene, (C2) alkenylene, or (C2) alkylyne; R8 is is hydrogen, halo, (C1-C8) alkoxy, (C1-C8) alkyl, nitro, amino, carboxy, mercapto, (C1-C4)thioalkyl, COCH3, CF3, OCF3, or SCF3, R9 is a cycloalkylene, cycloalkenylene, heterocyclylene, arylene, or hetroarylene; and R10 is a (C1-C8) alkylene, (C2-C8) alkenylene, or (C2-C8) alkylyne.
