Porphyrin-based conjugated microporous polymers have shown the huge application potential in energy storage systems, but the low conductivity limits the practical applications. In this work, copper porphyrin-linked conjugated microporous polymer (CuTAPP-CMP) is synthesized. Then CuTAPP-CMP is combined with greatly conductive carbon nanotubes (CNTs) by simple vacuum filtration strategy. The resulting CuTAPP-CMP/CNTs-3 shows the flexible property, which enables them to be the flexible electrodes for supercapacitors (SCs). Fortunately, the flexible electrode of CuTAPP-CMP/CNTs-3 shows the specific capacitance of 207.8 F g−1 at 1 A g−1 as well as long cycle performance over 3700 cycles at 20 A g−1. The good electrochemical properties could be due to the synergic action of the high conductivity of CNTs and the high pseudocapacitance of CuTAPP-CMP. Our work provides a way to open up high-performance organic electro-active materials for SCs.

构建铜卟啉连接的共轭微孔聚合物/碳纳米管复合材料作为超级电容器的柔性电极

卟啉基共轭微孔聚合物在储能系统中显示出巨大的应用潜力,但其低电导率限制了实际应用。在这项工作中,合成了铜卟啉连接的共轭微孔聚合物(CuTAPP-CMP)。然后通过简单的真空过滤策略将 CuTAPP-CMP 与高导电性碳纳米管 (CNT) 结合。所得的 CuTAPP-CMP/CNTs-3 显示出柔性,这使其成为超级电容器 (SC) 的柔性电极。幸运的是,CuTAPP-CMP/CNTs-3 的柔性电极在 1 A g -1 下显示出 207.8 F g -1的比电容以及在 20 A g -1 下超过 3700 次循环的长循环性能. 良好的电化学性能可能是由于 CNT 的高电导率和 CuTAPP-CMP 的高赝电容的协同作用。我们的工作提供了一种为 SCs 开发高性能有机电活性材料的方法。
