Quinoxaline is a heterocyclic structure and strong electron acceptor units because of symmetric unsaturated imine nitrogen. As a result various of conjugated polymers using quinoxaline derivatives have attracted attention due to the production of low band gap for efficient organic photovoltaics. In this study, the conjugated copolymer was synthesized by Suzuki polycondensation using phenothiazine and quinoxaline. In order to improve the solubility, we introduce alkoxy and alkyl chain in the polymer backbone. The structure, electrochemical and photovoltaic properties of polymers were analyzed by 1H-NMR, 13C-NMR, TGA, GPC, UV-vis, cyclic voltammetry and fabricated devices was measured. |
