直接芳基化缩聚（DArP）是一种新兴的合成方法，以环境友好且经济高效的方式生产共轭聚合物。我们现在报道了在微波辅助 DArP 条件下合成空穴传输共轭聚合物，即 DPP-OMe (Mn= 7.9 kg/mol) 和 DPP-F (Mn = 12.6 kg/mol)。这两种聚合物和先前合成的 3,6-Cbz-EDOT 作为介观钙钛矿太阳能电池中的空穴传输材料进行了评估。与Stille缩聚合成的3,6-Cbz-EDOT相比，DArP合成的3,6-Cbz-EDOT表现出更高的空穴迁移率和更好的光伏性能。此外，化学掺杂剂提高了短路电流密度（Jsc）和填充因子。
Direct arylation polycondensation (DArP) is an emerging synthetic method of producing conjugated polymers in an environmentally benign and cost-effective manner. We now report the synthesis of hole-transporting conjugated polymers, namely, DPP-OMe (Mn= 7.9 kg/mol) and DPP-F (Mn = 12.6 kg/mol), under microwave-assisted DArP conditions. These two polymers and the previously synthesized 3,6-Cbz-EDOT were evaluated as hole-transporting materials in mesoscopic perovskite solar cells. 3,6-Cbz-EDOT synthesized by DArP exhibited higher hole mobility and better photovoltaic properties than that synthesized by the Stille polycondensation. Moreover, chemical dopants improved the short-circuit current density (Jsc) and fill factor.
