摘要：
Two novel conjugated copolymers (P1 and P2) with donor-acceptor architecture, based on triphenylamine, benzodithiophene and thiazolothiazole (TTz), have been prepared by the Stille coupling reaction. Compared with alternative copolymer P1 with the single electron-withdrawing unit TTz, random copolymer P2 introduced another stronger electron-withdrawing unit benzothiadiazole intramolecularly. Incorporation of two different electron-withdrawing units on the backbone was proved to have a significant influence on the optical and electrical properties. Compared with P1, copolymer P2 has the wider absorption spectrum, lower bandgap, and therefore the better device performances.
