Over the past decades, numerous scientists have focused on designing complicated monomers, developing new synthesis protocols, and optimizing chemical structures for realizing high‐performance organic or polymer electronics and energy storage devices. However, much less attention has been paid to ionic‐ and radical‐rich porous organic films, which are essential components of aforementioned devices. In this study, an air‐stable, large‐area, free‐standing, and viologen‐linked ionic porous polymer (denoted as IPP‐V) film is developed in situ through electrochemical polymerization. This film is applied to a device by sandwiching it between indium tin oxide (ITO) and Au (i.e., ITO/IPP‐V/Au); the device exhibits a memristive behavior with an ON–OFF current ratio of ≈2. After the IPP‐V film is subjected to thermal pyrolysis at 500 °C, the as‐produced film (denoted as IPP‐V‐500) acts as an active material for an in‐plane micro‐supercapacitor and exhibits a high volumetric capacitance level of up to 4.44 F cm⁻³. This work not only offers a new and convenient strategy toward large‐area ionic porous polymer films for memristor, but also provides a new porous polymer derived carbon film for energy storage.

紫精-超交联的离子多孔聚合物薄膜作为电子和储能设备的活性层

在过去的几十年中，许多科学家致力于设计复杂的单体，开发新的合成方案以及优化化学结构，以实现高性能的有机或聚合物电子学和能量存储设备。但是，对富含离子和自由基的多孔有机膜的关注却很少，这是上述设备的基本组成部分。在这项研究中，通过电化学聚合原位开发了一种空气稳定，大面积，独立式和紫精连接的离子多孔聚合物（称为IPP-V）膜。该膜通过将其夹在氧化铟锡（ITO）和Au（即ITO / IPP-V / Au）之间而应用到设备上；该器件具有忆阻特性，开/关电流比约为≈2。将IPP-V薄膜在500°C下进行热解后，⁻³。这项工作不仅为忆阻器大面积离子化多孔聚合物膜提供了一种新的便捷策略，而且还为储能提供了一种新型的由多孔聚合物衍生的碳膜。
