2c06 Flying-seed-like Liquid Crystals (4) : Synthesis and Mesomorphism of Flying-seed-like Phthalocyanine-Fullerene Dyads

Abstract

Previously, we reported that a series of phthalocyanine (Pc) derivatives substituted by bulky aryl groups without long alkyl chains show columnar mesomorphism, and that they are novel flying-seed-like liquid crystals. These flying-seed-like liquid crystals may be applicable to solar cell, and they can be expected to show high conversion efficiency. In this work, we have, hence, synthesized novel dyads consisting of this flying-seed-like Pc and a fullerene to investigate their mesomorphism by using a polarizing microscope, a differential scanning calorimeter and a temperature-dependent X-ray diffractometer.
