通过将富电子芘核与缺电子二酮吡咯并吡咯（DPP）末端偶联，设计合成了三种新型的给电子小分子Pyr（EH-DPP）2、Pyr（HD-DPP）2和皮拉（EH-DPP）2，其衍生的有机太阳能电池表现出有趣的结构与性能相关性.结果表明，调节受体-供体-受体（A-D-A）SM的增溶侧链和π桥可以显著改变OSC的短路电流密度和功率转换效率（PCE）。具有短侧链的Pyr（EH-DPP）2比具有长侧链的Pyr（HD-DPP）2显示更宽的吸收和更高的空穴迁移率。虽然表现出平面结构，乙炔桥合并的皮拉（EH-DPP）2适应了不希望的边缘上的包装和强烈的聚集在膜中，导致非理想的形态和与富勒烯受体的相容性差。结果表明，基于Pyr（EH-DPP）2的太阳能电池的PCE是基于Pyr（HD-DPP）2和皮拉（EH-DPP）2的太阳能电池的PCE的数倍，表明聚芳族化合物与DPP的A-D-A组合将是开发光伏半导体的有前途的骨架。
Three new electron donating small molecules (SMs), Pyr(EH-DPP)2, Pyr(HD-DPP)2 and PyrA(EH-DPP)2, are designed and synthesized through coupling electron rich pyrene core with electron deficient diketopyrrolopyrrole (DPP) terminals, of which the derived organic solar cells (OSCs) exhibit interesting structure-performance correlation. It shows that the tune of their solubilizing side chains and π-bridge for the acceptor-donor-acceptor (A-D-A) SMs can significantly alter the resultant short-circuit current density and power conversion efficiency (PCE) in OSCs. The Pyr(EH-DPP)2 with short side chains displays broader absorption and higher hole mobility than the Pyr(HD-DPP)2 with long side chains. Although showing planar structure, the acetylene bridge-incorporated PyrA(EH-DPP)2 adapts an undesired edge-on packing and strong aggregation in film, leading to non-ideal morphology and poor miscibility with fullerene acceptors. As a result, the PCE of the solar cell based on Pyr(EH-DPP)2 is several times higher than those based on Pyr(HD-DPP)2 and PyrA(EH-DPP)2, indicating the A-D-A combination of polyaromatics with DPP would be the promising skeleton for developing photovoltaic semiconductors.
