The copolymer poly(3-(4-fluorophenyl)thiophene-co-3-methylthiophene) was successfully prepared from mixtures of 3-(4-fluorophenyl)thiophene (FPT) and 3-methylthiophene (MeT) via electrochemical oxidation in boron trifluoride diethyl etherate (BFEE) and its mixed electrolytes with acetonitrile (ACN). The influence of monomer concentration ratios on the copolymerization was investigated by using linear sweep voltammetry and cyclic voltammetry. The structure and morphology of these copolymer films were elucidated by UV-Vis, infrared spectroscopy, elemental analysis, thermal analysis and scanning electron microscopy (SEM), respectively. The results showed that the molar ratio of FPT and MeT units, when copolymer was electrodeposited from feed ratio of FPT:MeT = 1:2, was about 1.08:1. In addition, the introduction of ACN into BFEE has little effect on the properties of as-formed copolymers.
