摘      要：Side-chain engineering as one of the most important molecular design strategies has been widely used to improve photovoltaic effi-ciency of active layer ***,a series of acceptor-n-donor-n-acceptor typed small molecule(SM)-donors(SL1,SL2,SL3,and SL4),on the basis of high-performance SM-donor BTTzR(SL1)with thiazolo[5,4-d]thiazole as the n-bridging units and 3-butylrho-danine as the terminal electron-withdrawing groups,were designed and synthesized to study the effect of the side-chain substitu-tions of BDT-T on the photovoltaic performanee.
