为了开发基于可再生能源的工艺，研究人员对光诱导的有机转化越来越感兴趣。金属有机骨架（MOFs）是一类微孔/介孔杂化材料，由于其独特的结构特点，近年来成为一种新型的有机合成光活性材料。本文综述了mof作为光催化剂在光诱导有机转化中的最新应用，包括：(1)醇、胺、烯烃、烷烃和硫化物的氧化；(2)芳香族化合物如苯的羟基化反应；(3)活化C-H键，生成新的C-C或C-X键；(4)原子转移自由基聚合（ATRP）。本文首先介绍了mof用于光催化的一般背景信息，然后分别介绍了mof中光活性无机节点和光催化活性配体促进的光诱导有机转化。在此基础上，讨论了mof作为光诱导有机转化的多功能催化剂，通过金属/配体/客体催化的有效融合，其中mof的光催化活性起着关键作用。最后，讨论了mof在光诱导有机转化中的应用的局限性、挑战和未来展望。这篇综述的目的是为其他研究人员进入这个很大程度上未开发的领域提供一个起点。我们的目标是促进这一领域的深入研究，以合理设计MOF材料，克服其目前在光催化方面的局限性，从而导致更多创造性的可见光诱导有机转化。
With the aim of developing renewable energy based processes, researchers are paying increasing interest to light induced organic transformations. Metal-organic frameworks (MOFs), a class of micro-/mesoporous hybrid materials, are recently emerging as a new type of photoactive materials for organic syntheses due to their unique structural characteristics. In this Review, we summarized the recent applications of MOFs as photocatalysts for light induced organic transformations, including (1) oxidation of alcohols, amines, alkene, alkanes and sulfides; (2) hydroxylation of aromatic compounds like benzene; (3) activation of the C-H bonds to construct new C-C or C-X bonds; (4) atom-transfer radical polymerization (ATRP). This Review starts with general background information of using MOFs in photocatalysis, followed by a description of light induced organic transformations promoted by photoactive inorganic nodes and photocatalytic active ligands in MOFs, respectively. Thereafter, the use of MOFs as multifunctional catalysts for light induced organic transformations via an efficient merge of the metal/ligand/guest based catalysis where the photocatalytic activity of MOFs plays a key role are discussed. Finally, the limitations, challenges and the future perspective of the application of MOFs for light induced organic transformations were addressed. The objective of this Review is to serve as a starting point for other researchers to get into this largely unexplored field. It is also our goal to stimulate intensive research in this field for rational designing of MOF materials to overcome their current limitations in photocatalysis, which can lead to more creative visible-light-induced organic transformations.
