building blocks, 3D PDI molecules are considered as a type of promising structure to overcome molecular aggregation, thus improving the performance of organic solar cells. Herein, we report a novel PDI‐based derivative, SCPDT‐PDI4, with four PDI units connected to a unique spiro core. Attributed to this novel molecular design, SCPDT‐PDI4 exhibits a rigid 3D structure, in which the aggregation tendency
3D PDI分子衍生自per二
酰亚胺(PDI)构件,被认为是克服分子聚集的一种有前途的结构,从而提高了有机太阳能电池的性能。本文中,我们报告了一种新颖的基于PDI的派生工具
SCPDT-PDI 4,其中四个PDI单元连接到一个独特的螺旋核。由于这种新颖的分子设计,
SCPDT-PDI 4呈现出刚性的3D结构,其中PDI发色团的聚集趋势可以被有效地减弱。此外,由于
SCPDT的良好共轭结构和富电子特性,可实现强大的分子内电荷转移和高电荷迁移率。因此,基于
SCPDT-PDI 4的不含
富勒烯的有机太阳能电池PTB7-Th的效率高达7.11%。如此出色的结果表明,
SCPDT有机会成为非
富勒烯受体的有前途的基石。
