Abstract Organic‐ligand‐containing frameworks have drawn considerable attention due to their multifunctional properties as well tunable structures for broad applications. Among numerous synthesis methods developed in the past two decades, electrochemical processing has been demonstrated one of most efficient, safe, and facile ways realize large‐scale highly controllable production organic‐ligand‐containing frameworks. In this review, progress electrochemically induced crystallization thin film fabrication is summarized a well‐rounded way. Besides, mechanism parameters are also discussed. Moreover, main challenges expounded providing some guidance on future development frameworks, especially covalent‐organic hydrogen‐bonded organic

Abstract Covalent organic frameworks (COFs) with periodic channels and tunable chemical structures have been widely considered as promising electrode materials in rechargeable batteries. However, the design construction of high‐performance COFs‐based electrodes still face some challenges introduction multiple efficient redox centers well reduction dead mass. To address these issues, a unique COF containing double active (C═N N═N) is developed an anode lithium‐ion batteries (LIBs). The as‐prepared displays excellent electrochemical performance due to its remarkable structural stability existence many groups. Meanwhile, significantly better than that small molecule compound or linear polymer same units. Even at high current density 5 A/g, LIBs remain discharge capacity 227 mAh/g after 2000 cycles. Moreover, distinction performances three further revealed by calculation. This study illustrates importance molecular structure for improving electrodes.
