A polymer acceptor, named PX-1, is designed and synthesized using a polymerization strategy with grafted small molecule acceptors. This design approach allows for the freedom of end groups while maintaining efficient terminal packing, enhancing π-π interactions, and facilitating charge transport. All-polymer organic solar cells based on PM6: PX-1 demonstrate a promising efficiency of 13.55%. The result presents an alternative pathway for the design of high-efficiency polymer acceptors through the careful regulation of small molecule acceptor monomers and linker units.
一种名为 PX-1 的聚合物受体，是通过使用接枝小分子受体的聚合策略设计和合成的。这种设计方法在保持高效端基堆积的同时，允许端基自由，增强π-π相互作用，并促进电荷传输。基于 PM6:PX-1 的全聚合物有机太阳能电池表现出 13.55%的有前景的效率。该结果通过仔细调节小分子受体单体和连接单元，为设计高效聚合物受体提供了一种替代途径。
