In the last two decades, metal-organic frameworks (MOFs), as a class of porous crystalline materials formed by organic linkers coordinated-metal ions, have attracted increasing attention due to their unique structures and wide applications. Compared to single components, various well-designed MOF-based composites combining MOFs with other functional materials, such as nanoparticles, quantum dots, natural enzymes and polymers with remarkably enhanced or novel properties have recently been reported. To efficiently and directionally synthesize high-performance MOF-based composites for specific applications, it is vital to understand the structural-functional relationships and role of MOFs. In this review, preparation methods of MOF-based composites are first summarized and then the relationship between the structure and performance is determined. The functions of MOFs in practical use are classified and discussed through various examples, which may help chemists to understand the structural-functional relationship in MOF-based composites from a new perspective.
在过去二十年中，金属有机框架材料（MOFs）作为一类由有机连接体与金属离子配位形成的多孔晶体材料，因其独特的结构和广泛的应用而受到越来越多的关注。与单一成分相比，最近有报道称，各种精心设计的将MOFs与其他功能材料（如纳米颗粒、量子点、天然酶和聚合物）相结合的基于MOF的复合材料具有显著增强的性能或新颖的特性。为了高效、定向地合成用于特定应用的高性能基于MOF的复合材料，了解MOFs的结构-功能关系及其作用至关重要。在这篇综述中，首先总结了基于MOF的复合材料的制备方法，然后确定了结构与性能之间的关系。通过各种实例对MOFs在实际应用中的功能进行了分类和讨论，这可能有助于化学家从新的角度理解基于MOF的复合材料中的结构-功能关系。
