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 BF 3 ‐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.
