A chiral azobenzene dopant with helical twisting power has a structure represented by the following formula (I): wherein Z and Z' are independently selected from the group consisting of naphthalene and phenanthrene; when Z or Z′ is naphthalene, the naphthalene optionally has Rat the 6 position and Rat the 6′ position; when Z or Z′ is phenanthrene, the phenanthrene optionally has Rat the 7 position and Rat the 7′ position; R, R, R, and Rare independently selected from the group consisting of an alkyl group having 1 to 20 carbons, an alkoxy group having 1 to 20 carbons, an aryl group having 6 to 20 carbons, and an aryloxy group having 6 to 20 carbons; and on any R, R, R, and R, on any CHa CHis optionally attached by replacing a hydrogen on a CH.
