英文摘要	Two novel solution-processed acceptor-donor-acceptor (A-D-A) structured organic molecules with 5,8-disubstituted benzo[1,2-b:4,5-b']dithiophene (BDT or BDTT) as central and donor units, 2(1,1-dicyanomethylene)rhodanine (DCRD) as acceptor unit and terminal group, and trithiophene (T-3) as pi-bridges, D(T-3-DCRD)-BDT and D(T-3-DCRD)-BDTT, are designed and synthesized for the application as donor materials in organic solar cells (OSCs). Both compounds exhibit broad absorption covering the wavelength range 300-750 nm and the relatively lower HOMO energy levels from -539 to -5.46 eV. D(T-3-DCRD)-BDTT demonstrates strong absorbance and higher hole mobility than that of D(T-3-DCRD)BDT. The power conversion efficiency (PCE) values of the OSCs based on the compounds/PC61BM (1:1, w/w) are 1.10% for D(T-3-DCRD)-BDT and 1.94% for D(T-3-DCRD)-BDIT, under the illumination of AM. 1.5G, 100 mW/cm(-2). Furthermore, the high open-circuit voltage (V-oc) values are 0.93 V for D(T-3-DCRD)-BDT and 0.96 V for D(T-3-DCRD)-BDTT, respectively. It indicates that incorporating DCRD as an acceptor unit into D-A-D-type small molecule has proven to be promising candidates for high efficiency solution processed OSCs. (C) 2015 Elsevier Ltd.
