氧化还原聚合物可逆地释放电子（经历氧化）并获得电子（经历还原）。从研究其独特的电化学能力及其在各种电荷存储装置和氧化还原催化剂应用中的用途的角度来看，有机氧化还原聚合物的化学设计非常有趣。本综述首先介绍有机氧化还原分子的快速电子交换反应及其氧化和还原形式的双稳定性，然后讨论了含有密集氧化还原活性位点的主链的氧化还原聚合物中有效且可逆的电荷传播和存储。然后讨论了在可充电电荷存储装置中使用氧化还原聚合物作为氢载体，以及从水中电化学生产过氧化氢、氢气和氧气，包括最近的例子，包括柔性和高功率电池、电极活性生物材料和太阳能驱动的催化薄膜。氧化还原聚合物的优势还体现在源自相对丰富的资源的无生物危害的有机材料及其在环保应用中的功能。本综述提供了对氧化还原聚合物特性的基本见解，并有望刺激其作为用于能源相关技术的可持续材料的发展。
Redox polymers reversibly release electrons (undergo oxidation) and gain electrons (undergo reduction). The chemical design of organic-based redox polymers is very interesting from the perspectives of studying their unique electrochemical capabilities and their use in a variety of charge-storage-device and redox-catalyst applications. This review begins by introducing the rapid electron-exchange reactions of organic redox molecules and the bistability of their oxidised and reduced forms, followed by a discussion on efficient and reversible charge propagation and storage in redox polymers containing backbones that are densely populated with redox-active sites. Employing redox polymers in rechargeable charge-storage devices, as hydrogen carriers, and for the electrochemical production of hydrogen peroxide, hydrogen, and oxygen from water is then discussed, including more-recent examples that include flexible and high-power batteries, electrode-active biomaterials, and solar-driven catalytic films. The advantages of redox polymers are also noted in terms of non-biohazardous organic materials that are derived from relatively-abundant resources, as well as their functions in environmentally-friendly applications. This review provides basic insight into the characteristics of redox polymers, and is expected to stimulate their development as sustainable materials for use in energy-related technologies.
