Covalent organic frameworks (COFs) have emerged as a new class of crystalline porous materials prepared by integrating organic molecular building blocks into predetermined network structures entirely through strong covalent bonds. The consequently encountered "crystallization problem" has been conquered by dynamic covalent chemistry in syntheses and reticular chemistry in materials design. In this contribution, we have reviewed the progress in the crystallization of COF materials and their hydrogen, methane and carbon dioxide gas storage properties for clean energy applications.

共价有机框架（COFs）作为一类新型的结晶多孔材料，是通过将有机分子构建块完全通过强共价键集成到预定的网络结构中制备的。在合成中采用动态共价化学，在材料设计中采用网状化学，克服了由此产生的“结晶问题”。在本贡献中，我们综述了 COF 材料的结晶及其在清洁能源应用中的氢气、甲烷和二氧化碳气体存储性能的研究进展。
