ABSTRACT:
A glassy thermotropic chiral nematic liquid crystalline composition comprises a glassy chiral nematic compound of low molar mass that includes a cycloaliphatic radical, a nematogenic moiety, and a chiral moiety, or a mixture of a nematic liquid crystalline compound of low molar mass that includes a cycloaliphatic radical and a nematogenic moiety and a chiral compound of low molar mass that includes a cycloaliphatic radical and a chiral moiety. Each cycloaliphatic radical contains 4 to about 18 carbon atoms. An optical device is formed from the described glassy thermotropic chiral nematic liquid crystalline composition.
