Electrochemical copolymerization of furan and 3-chlorothiophene was performed at constant electrode potential in a binary
solvent system consisting of boron trifluoride diethyl etherate + ethyl ether (BFEE + EE; ratio 1:2) and trifluoroacetic acid
(10% by volume). The homopolymers and copolymers obtained were studied with cyclic voltammetry, in situ ultraviolet–visible
spectroscopy, in situ resonance Raman spectroscopy, and in situ conductivity measurements. The spectroelectrochemical properties
of the copolymers show intermediate features between polyfuran and poly(3-chlorothiophene). The conductivity changes of homo-
and copolymer films are almost completely reversible when the potential shift direction is reversed.

In situ UV/VIS spectroscopy of selenophene? thiophene homo‐ and copolymer films had been investigated. λ corresponding to the π→π* interband transition was determined. The optical transition with λ from the valence band into the higher bipolaron band was also allocated. Besides, band gap energy (Eg) of the individual homopolymer and the obtained copolymer films from a direct interband transition was estimated as well, and the values were between 1.91–2.10 eV. The influence of applied polymerization potential and monomer feed ratio on the optical properties of the copolymers is discussed. 相似文献
