Abstract

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.
