作为一类新兴的结晶有机材料，共价有机骨架（COF）具有均匀的孔隙率，多功能性，以及对指定结构的精确控制。除了多孔框架提供的有利的电荷和质量传输途径之外，COFs还可以表现出设计的可逆氧化还原活性。在过去的几年中，它们的潜力已经吸引了大量的注意力，在各种电化学能量存储设备中的电荷存储和传输应用，并且已经提出了许多设计策略来增强相应的电化学性能。本文综述了COFs的工作原理和合成方法，并讨论了在超级电容器和各种可充电电池系统中的重要发现，强调了代表性的设计策略及其与电化学性能的潜在关系。此外，还沿着介绍了计算所取得的重要进展，以及该领域面临的挑战和前景。
As an emerging class of crystalline organic material, covalent organic frameworks (COFs) possess uniform porosity, versatile functionality, and precise control over designated structures. Aside from the favorable charge and mass transport pathways offered by the porous framework, COFs can also exhibit designed reversible redox activity. In the past few years, their potential has attracted a great deal of attention for charge storage and transport applications in various electrochemical energy storage devices, and numerous design strategies have been proposed to enhance the corresponding electrochemical properties. This review summarizes the working principle and synthesis methods of COFs and discusses significant findings for supercapacitors and various rechargeable battery systems, emphasizing the representative design strategies and their underlying relationship with electrochemical performances. In addition, key advances achieved by computations are highlighted along with the challenges and prospects in this field.
