The phase transition behaviour of an octaoctadecylthiophthalocyanine and its Cu and V=O complexes was studied in terms of melting behaviour and intracolumnar structutre. All these compounds show hexagonal disordered columnar mesophase. However, the metal-free and Cu complex exhibit complicated melting behaviour strongly depending on cooling process from the mesophase, whilst the V=O complex does not. XRD studies on these compounds indicated the difference of intracolumnar structure and/or molecular dynamical situation in a column between V=O complex and the other. These results imply that the central part of disc-shaped mesogen certainly influences on molecular stacking manner in columns, which could lead to remarkable difference in charge migration phenomena.
