Abstract

The electrochemical polymerization of 3‐methylthiophene was significantly facilitated by the presence of freshly distilled boron fluoride‐ethyl ether as supporting electrolyte and stainless steel as electrode during the polymerization. The lower oxidation potential of the monomer led to high overall stereoregularity and stacking order of poly(3‐methylthiophene) chains. A current density of 1 mA/cm^2^ and a monomer concentration of 35–70 mmol/L turned out to be optimal electrosynthesis conditions. Poly(3‐methylthiophene) films had high tensile strength (73 MPa) and flexibility. The high stereoregularity of poly(3‐methylthiophene) resulted in high conductivity with improved environmental stability.

## Abstract Electrochemical copolymerization of __o__‐dihydroxybenzene (__o__DHB) and 3‐methylthiophene (3MeT) was successfully achieved in boron trifluoride diethyl etherate by direct anodic oxidation of the monomer mixtures, although the oxidation potentials of __o__DHB and 3MeT were quite differ
