A novel polythiophene having an ionic viologen mesogenic side chain at the 3-position was synthesized from a 2,5-dibromo-thiophene derivative by dehalogenative polycondensation using Ni(cod)2. Redox function of the viologen moiety in the polymer was confirmed by cyclic voltammetry. The polymer showed liquidcrystalline, electrical conductive and photoelectrical properties.
