Pyradinodithiazole (PDTz) was designed as a new electron-accepting unit. The physical property measurements indicated that the PDTz unit has stronger electron-accepting characteristics than thiazolothiazole and benzodithiazole. A donor鈥揳cceptor copolymer containing PDTz as an acceptor unit was synthesized for hole-transporting semiconductors in organic photovoltaics (OPV). Furthermore, an acceptor鈥揳cceptor copolymer containing PDTz has also been developed for electron-transporting OPV materials. These copolymer-based blend films showed expected photovoltaic characteristics in individual OPV devices.
