A new electrochemical route to polythiophene (PT) films with an electrical conductivity between 800 and 1300 S cm–1 and a mechanical strength of 135 MPa is reported. The PT polymerization was performed in a BF3-ethyl ether solvated Lewis acid solution in the presence of the proton scavenger 2,6-di-tert-butylpyridine. The prepared PT films are shown to possess relatively regular molecular structure and inter-chain packing. The resulting microscopic structure enhances the macroscopic properties of the PT films.
