Summary: A novel thiophene‐based conducting copolymer has been synthesised with mesogenic groups attached parallel to the conducting polymer backbone; preliminary data are reported on its properties. These indicate that as the nonmesogenic intermediate polymer is converted into a liquid‐crystalline polymer there is a significant increase in conductivity. Measurement of the temperature‐dependent conductivity indicates a reduction of the activation energy in the liquid‐crystalline phase.Poly[(1‐(thiophene‐3‐methyloxy)‐6‐(4‐ n ‐hexyloxy‐2‐oxybenzoic acid)hexane)‐ co ‐(3‐ n ‐hexylthiophene)].
