Three kinds of liquid crystalline compounds (AQBD1, AQBD2 and AQBT) having an anthraquinone and a bithiophene moieties were synthesized. The mesophases have been characterized by polarized optical microscopy (POM) observation, differential scanning calorimetry (DSC) and X-ray diffraction (XRD) studies. AQBD1 and AQBT were determined to form colomnar phases while AQBD2 showed a smectic phase. The disc units of the columnar phases of AQBD1 and AQBT were expected to contain 2 and 3 molecules, respectively. The electrochemical properties of AQBT, which keeps the liquid crystalline phase at room temperaure, were examined by cyclic voltammetry (CV) and optoelectrochemical measurements. The reversible electrochemical response of AQBT was confirmed in solution. The reversible color change of EC device prepared from liquid crystalline AQBT (LC-AQBT) was also observed at room temperaure and the positive potentials, which is due to the bithiophene unit.
