Two novelacceptors of benzo[c][1,2,5]thiadiazole and quinoxaline with conjugateddithienylbenzothiadiazolependants were first designed and synthesized for building efficient photovoltaiccopolymers. Based on benzo[1,2‐b;3,4‐b′]dithiophene donors and the two acceptors, two new copolymers have been prepared by Stille coupling polymerization. The resulting copolymers were characterized by 1H NMR, gel
