A novel copolymer Poly (bithiopheneco-methylfuran) has been synthesized by electrochemical oxidation of the monomer mixtures of bithiophene and methylfuran in acetonitrile (CH₃CN) containing lithium perchlorate as supporting electrolyte (LiClO₄) doped on indium-tin- oxide (ITO) glass plates. The electrochemical properties of the obtained copolymers are studied by cyclic voltammetry (CV), UV-visible spectroscopy, scanning electron microscopy (SEM), conductivity measurement and photocurrent measurement techniques. The optical properties show that the copolymerization in the presence of bithiophe and 2-methyl furan, results in a bathochromic shift of the absorption maximum, the photocurrent measurement shows good photoelectrochemical properties of this copolymer makes it ideal candidates for photovoltaic cells applications.
