Redox‐Active Porous Organic Polymers for Energy Storage

This review introduces synthesis and energy storage applications of recent redox‐active porous organic polymer (POP) materials. First, various redox‐active molecular systems were summarized and then, synthetic examples of redox‐active POP bearing the redox‐active molecular moieties were described. Various synthetic strategies based on diverse coupling reactions of building blocks were described. In addition, postsynthetic modification strategies for the preparation of redox‐active POP were described. Second, structures and electrochemical features of battery and pseudocapacitor devices were introduced. Then, electrochemical performance of various redox‐active POP materials was summarized and described. Finally, merits and weak points of redox‐active POPs as electrode materials were discussed and future research direction was suggested. Redox‐active porous organic polymer (POP) has been applied as electrical energy storage electrode materials for batteries and pseudocapacitors. The high surface area, porosity, chemical stability, and chemical diversity are striking merits of redox‐active POP in the development of electrode materials. The synthetic strategies and electrochemical performance of the redox‐active POP are introduced in this review paper.
