Abstract

A novel chiral inducer having a donor-acceptor-donor structure was synthesized. Its rigid structure allows an increase of miscibility and helical twisting power for the host liquid crystal. The donor-acceptor-donor structure allows visible light absorption. Electrochemical polymerization of an achiral monomer was performed in a cholesteric liquid crystal induced by the inducer. The chiral inducer molecules alone showed right-handed helical aggregation in the solid state, while the inducer produces a left-handed helical arrangement of cholesteric liquid crystals in a nematic liquid crystal. The resultant conjugated polymer films showed circular dichroism and left-handed helical aggregation. Film surfaces displayed a periodic convex-concave structure that was transcribed from the fingerprint texture of the cholesteric liquid crystal electrolytes during the polymerization process.
