Porous organic polymers (POPs) with nitrogen-enriched structures are the type of materials with the advantages of porosity, excellent stability, and wide synthetic pathways, which possesses the great potential for application in the proton conduction. Herein, we report the synthesis of a novel type of pyrrole-based POPs that exhibit high surface areas and nitrogen-rich skeletons. The fabricated pyrrole-linked POPs render the high potential for the proton conducting application. In order to achieve precise modulation of the polymer structures, a benzothiadiazole moiety was introduced to increase the active site for forming strong hydrogen bonds with phosphoric acid. This modification allowed for precise manipulation of the monomers, which achieves a proton conductivity of 38.0 mS cm at 180 °C. This work demonstrates a new type of nitrogen-rich POPs for proton conduction applications.
具有富氮结构的多孔有机聚合物（POPs）是一类具有孔隙率高、稳定性好和合成途径广泛等优点的材料，在质子传导方面具有巨大的应用潜力。在此，我们报道了一种新型吡咯基POPs的合成，该材料具有高比表面积和富氮骨架。制备的吡咯连接的POPs在质子传导应用方面具有很高的潜力。为了实现聚合物结构的精确调控，引入了苯并噻二唑部分以增加与磷酸形成强氢键的活性位点。这种修饰使得对单体的精确控制成为可能，从而在180°C时实现了38.0 mS cm的质子传导率。这项工作展示了一种用于质子传导应用的新型富氮POPs。
