Abstract

Sesamin was employed as a chiral dopant for preparing cholesteric liquid crystals with right-handed helical architecture. Helical twisting power of sesamin is to be 13.4 μm−1. Electrochemical polymerizations were carried out with sesamin-induced cholesteric liquid crystal electrolyte solution for obtaining conjugated polymer films with helical structure. The film was transcribed the helical order from the liquid crystal electrolyte solution with helical structure produced by sesamin during the polymerization process. The helical axes of the macromolecular superstructure of the polymer films were oriented in a magnetic field of 4.5 T. This results demonstrated liquid crystal magneto-electrochemical polymerization with helical structure induced by sesamin as a natural chiral compound.
