In order to circumvent the contradiction between processability and electrochemical performances, we report a recombination strategy in both unit and segment scales for processable ambipolar electroactive materials starting from parental moieties: classic ambipolar polymer (PEBE) and its soluble analogue (PPBP). On the basis of this strategy, two recombined polymers (PEB-P and PEBE-PBP) are successfully prepared via direct (hetero)arylation copolymerization. Through systematical characterization of properties, both PEB-P and PEBE-PBP not only possess the solubility fostered by PPBP but also exhibit identical electrochemical and optical properties to PEBE, demonstrating the reliability of this recombination strategy. Moreover, film electrodes of these recombined polymers exhibit desirable pseudocapacitance, acceptable stability, and superior processability to PEBE, making them promising candidates for Type III supercapacitors and other multifunctional energy storage devices.

伪电容器中可加工的双极性电活性聚合物的重组策略

为了规避可加工性和电化学性能之间的矛盾，我们报告了从亲代基团开始的可加工双极性电活性材料在单位和片段尺度上的重组策略：经典双极性聚合物（PEBE）及其可溶性类似物（PPBP）。在此策略的基础上，通过直接（杂）芳基化共聚成功制备了两种重组聚合物（PEB-P和PEBE-PBP）。通过特性的系统表征，PEB-P和PEBE-PBP不仅具有PPBP促进的溶解性，而且还具有与PEBE相同的电化学和光学性质，证明了这种重组策略的可靠性。此外，这些重组聚合物的薄膜电极表现出理想的拟电容，可接受的稳定性，
