2c04 Discotic Liquid Crystals of Organic Metal Complexes (108) : Synthesis and Mesomorphism of Dyads Consisting of Fullerene and Phthalocyanine Substituted by Phenoxy Group Having Three Alkoxy Chains

Abstract

Previously, we prepared the phthalocyaninato copper(II) complexes substituted by eight p, m, m'-trialkoxyphenoxy groups, abbreviated as [(C_nO)_3PhO]_8PcCu, which show a wide temperature range of Cubic mesophase irrespective of a disk-like molecule. Cubic phases are still unclear and fascinating mesophases. There have been only four examples showing Cubic phases in discotic liquid crystals including this [(C_<14>O)_3PhO]_8PcCu complexes. In this work, we have successfully synthesized a novel phthalocyanine-fullerene dyad, [(C_<14>O)_3PhO]_6PcCu-C_<60>(1), and investigated the mesomorphism.
