In this work, we synthesized thiophene monomers containing a mesogenic group at 3-position of the thiophenering in order to incrcease the solubility and the fusibility. Polymers were obtained by the polycondensation reaction with zero valence nickel, zero valence paradium, or zinc, as a catalyst, and examined their phase transition behaviors and electrochemical properties. The polymers were soluble in organic such as chloroform, THF, toluene, DMF. The mesomorphic properties of the polymers were investigated by differential scanning calorimetry and polarized optical microscopy. The polymers containing cyanobiphenyl or cyanophenyl benzoate exhibited nematic phase, while smectic phase showed for the ester bond type polythiophene. The electrochemical properties of the polymers were examined by cyclic voltammogram measurement. The polymers were identified that they were electrochemically active.
