Highlights•Two small-molecule acceptors 1CIC and 2CIC based on CPDT units and 1,1-dicyanomethylene-3-indanone were synthesized.•Compared with 1CIC, 2CIC exhibited stronger NIR absorption, higher HOMO and LUMO energy levels, and higher electron mobility.•Nonfullerene solar cell based on PTB7-Th:2CIC gave a PCE of 3.53%, with a Jsc of 10.97 mA/cm2.
