Abstract
A liquid crystal composition comprising a chiral dopant compound represented by the following structure (Structure 1): wherein: R1 and R2 are independently hydrogen, —(C═O)R9, —(C═O)R10, alkyl, aryl, alkaryl, alkenyl, cycloalkyl, alkoxyaryl, or heterocyclic all either substituted or unsubstituted, or combine to form a carbocyclic or heterocyclic ring; and R3-R9 are as described in the disclosure. Also featured are liquid crystal compositions comprising a chiral dopant compound represented by any of Structure 2-4 as described in the disclosure.
