通过Stille聚合合成了两种基于稠合苝二酰亚胺（PDI）和联噻吩或二氟联噻吩单元的聚合物电子受体（PFPDI-2T和PFPDI-2FT）。两种聚合物在350~650 nm范围内均表现出较强的吸收，与聚合物太阳能电池（PSC）中的低带隙共轭聚合物具有良好的吸收补偿。 PFPDI-2T和PFPDI-2FT的LUMO能级约为-4.12至-4.15 eV，与其他基于PDI的聚合物和富勒烯衍生物相当。以 PFPDI-2T 或 PFPDI-2FT 作为聚合物电子受体，以 PTB7-Th 作为聚合物电子供体制备全聚合物太阳能电池（all-PSC）。在模拟太阳光标准照度（AM 1.5，100 mW cm-2）下，基于 PFPDI-2T/PTB7-Th 的功率转换效率高达 6.39%，明显高于基于非融合 PDI 的全 PSC。结果表明，PDI 单元的直接融合是一种有效的...
Two polymeric electron acceptors (PFPDI-2T and PFPDI-2FT) based on the fused perylene diimide (PDI) and bithiophene or difluorobithiophene units were synthesized via the Stille polymerization. Both polymers exhibit the strong absorption between 350 and 650 nm, which have the good absorption compensation with the low band gap conjugated polymer in polymer solar cells (PSCs). PFPDI-2T and PFPDI-2FT have the LUMO energy levels of around −4.12 to −4.15 eV, which are comparable with other PDI-based polymers and fullerene derivatives. All-polymer solar cells (all-PSCs) based on PFPDI-2T or PFPDI-2FT as the polymeric electron acceptor were fabricated with PTB7-Th as the polymeric electron donor. Power conversion efficiency of as high as 6.39% based on PFPDI-2T/PTB7-Th was achieved under the standard illumination of simulated sunlight (AM 1.5, 100 mW cm–2), which is significant higher than that of the all-PSC based on the nonfused PDI counterpart. The results demonstrate that the direct fusion of PDI unit is an e...
