摘要：

We have synthesized a novel liquid crystalline conductive polythiophene derivative through dehalogenative polycondensation of 2,5-dibrominated thiophene monomer with a liquid crystalline substituent at 3-position of thiophene ring. The polymer is fusible and soluble in some organic solvents and has weight-average and number-average molecular weights of 8 x 10(4) and 4 x 10(4), respectively. Polarizing microscope of the polymer exhibits schlieren and droplet textures in the cooling process of 110 similar to 130 degrees C, demonstrating a formation of monotropic nematic liquid crystalline phase in the polymer.
