Synthesis and Mesomorphic Properties of Long-Chain Tetraphenylporphyrin Molybdenum Complexes

Abstract

New Liquid crystals of long-chain tetraphenylporphyrin oxomolybdenum (V) camplexes were synthesised and investigated on the mesomorphic phase transitions. DSC, X-ray and microscopic techniques revealed these exhibit mesomorphic properties. The mesomorphic phase transitions are likely to change depending on the identity of axial ligand(Cl, OH, OMe and OEt), indicating the axial ligand could crucially affect the mesomorphic behaviour.
