Redistributing the Electronic States of 2D‐Covalent Organic Frameworks for Electrochemical Energy Applications

Abstract Exploration of significantly active functional materials is highly valued for designing efficient electrochemical energy devices. 2D‐covalent organic frameworks (2D‐COF) have attracted significant interest in the context of important electrochemical applications due to their tunable structural and electronic properties, high thermal/chemical stability, and their carbon‐based motifs. The present review highlights the strategies and properties of modifying 2D‐COF electronically in detail and their prospects in electrochemical devices. The review clearly explains the electronic actuation methods of the COF skeletons by various synthetic and post‐synthetic strategies. The review crucially elucidates the importance of electroactive 2D‐COF as emerging functional materials in practical applications of electrochemical energy conversion devices. The review concludes by summarizing the effective strategies of 2D‐COF in improving electrocatalytic applications and suggests future research scope. The review orients the electroactive 2D‐COFs for critical analysis as advanced functional materials for a sustainable and reliable future.
