Two indaceno[1,2-b:5,6-b′]difuran-based non-fullerene acceptors (NFAs) IDF-IC and IDF-4F were designed and synthesized. IDF-IC and IDF-4F showed strong absorptions in the visible and near-infrared (NIR) region with narrow bandgaps of 1.56–1.62 eV. The power conversion efficiencies (PCEs) of PM6:IDF-IC and PM6:IDF-4F devices were 7.80% and 7.81%, respectively, with open-circuit voltages (V_oc’s) of 0.905 and 0.736 V, short-circuit current densities (J_sc’s) of 14.55 and 17.49 mA/cm², and fill factors (FFs) of 59% and 61%. These results demonstrate that the fused-ring furan-based NFAs could be one of the promising building blocks in constructing high performance NFAs.

基于茚达蒽二呋喃的非富勒烯电子受体，可用于高效聚合物太阳能电池

设计并合成了两种茚并[1,2- b：5,6- b ']二呋喃基非富勒烯受体（NFA）IDF-IC和IDF-4F。IDF-IC和IDF-4F在可见光和近红外（NIR）区域显示强吸收，带隙为1.56-1.62 eV。PM6：IDF-IC和PM6：IDF-4F器件的功率转换效率（PCE）分别为7.80％和7.81％，开路电压（V _oc）为0.905和0.736 V，短路电流密度（J _sc）为14.55和17.49 mA / cm ²，填充系数（FFs）为59％和61％。这些结果表明，基于稠环呋喃的NFA可能是构建高性能NFA的有希望的组成部分之一。
