A liquid crystal composition comprising a chiral dopant compound represented by the following formula:
wherein:
R1, R2 are independently aryl, alkyl, alkenyl, cycloalkyl, alkoxyaryl, alkaryl or heterocyclic all either substituted or unsubstituted, or combine to form a carbocyclic or heterocyclic ring; R3 and R4 are independently hydrogen, halogen, cyano, alkoxy, NHCOR7, NHSO2R7, COOR7, OCOR7, aryl, alkyl, alkenyl, cycloalkyl, alkoxyaryl, alkaryl or heterocyclic all either substituted or unsubstituted, or combine with either R1 or R2 to form a carbocylic or heterocyclic ring;
R5 and R6 are independently hydrogen, CH2, CH, alkyl or aryl either substituted or unsubstituted, COOR7, or combine with L to form a carbocyclic or heterocyclic ring;
R7 is aryl, alkyl, alkenyl, cycloalkyl, alkoxyaryl or heterocyclic all either substituted or unsubstituted;
L is the non-metallic elements required to form a carbocyclic or heterocyclic ring, or a single bond or a double bond;
m is 1-3;
n is 0-12.
