| Abstract: | 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. |
