Because of their potential to enable mass production of flexible, cost-effective, and large-area device applications, organic photovoltaic (OPV) devices which can be fabricated by simple solution processing techniques are under intense investigation in academic and industrial laboratories. However, most of the research has been focused on solution-processed polymer bulk-heterojunction (BHJ) solar cells. Compared with polymer-based OPVs, small molecule OPVs (SM-OPVs) possess some important advantages, including (1) uniform and defined molecular structures, resulting in less batch-to-batch variation; (2) generally higher open-circuit voltage (Voc); (3) higher hole mobility than the corresponding polymer materials; and (4) structural flexibility with simple control of energy levels via slight chemical structure modifications. In this work, to resolve problems of polymeric materials, we have designed and synthesized new low bandgap A1-π-A2-D-A2-π-A1 type small molecules, which terminal electron-withdrawing octyl cyanoacetate group is connected to a carbazole dimer core through another electron-accepting benzo[c][1,2,5]thiadiazole unit, for solution-processable SM-OPVs.
