Covalent organic frameworks (COFs), as an emerging class of crystalline porous polymers connected by dynamic covalent bonds, have been well studied over the past decade. Recently, three dimensional (3D) COFs have attracted extensive interest for the synthesis and applications of novel COFs. The principal reason for this rising trend is based on their unique porous features and excellent performances compared to previously reported two dimensional (2D) frameworks with the layered AA-stacking mode. This critical review describes the current state-of-the-art development of 3D COFs in the design principles, synthetic methods, functionalization strategies, and potential applications. Some major challenges associated with future perspectives are further discussed, inspiring the development of 3D COFs.
共价有机框架（COFs）作为一类通过动态共价键连接的新型结晶多孔聚合物，在过去十年中得到了深入研究。最近，三维（3D）COFs在新型COFs的合成与应用方面引起了广泛关注。这种上升趋势的主要原因是与先前报道的具有层状AA堆积模式的二维（2D）框架相比，它们具有独特的多孔特性和优异性能。这篇综述描述了三维COFs在设计原则、合成方法、功能化策略和潜在应用方面的当前最新进展。还进一步讨论了与未来展望相关的一些主要挑战，以推动三维COFs的发展。
