Abstract
A octaoctadecylthiophthalocyanine and the Cu(II) and V=O(IV) complexes were synthesised and investigated on the mesomorphic phase transition behaviour. All these compounds exhibit discotic hexagonal disordered columnar (Dhd) mesophase. The clearing points were strongly dependent on the central metal species and the order is in V=O > Cu > metal-free, although the melting points do not show any marked difference at the temperature around 50℃. This indicates the presence of specific intermolecular interaction derived from the metal species in the mesophase.
