Discotic Liquid Crystals of Organic Material Complexes (93): Synthesis and properties of donor-acceptor dyad discotic liquid crystals

Abstract

Our purpose is to synthesize the compounds having both donor and acceptor moieties and showing mesophase. We previously reported a donor-acceptor dyad discotic liquid crystal incorporated fullerene and phthalocyanine. However, there were problems that one, two and three Pc moieties were substituted to fullerene at the same time. Therefore, we have developed novel synthetic method to obtain the pure target dyad in high yield. Furthermore, the novel material showed columnar liquid crystalline property, and homeotropic alignment.
