摘　　要：金属-有机笼状化合物(MOCs)是一种由金属离子与有机配体通过配位自组装而成的具有特定空腔的化合物。MOCs的可变价金属离子、功能性配体和形状各异的空腔结构为催化不同反应提供了条件,MOCs的限域催化作用实现了对不同类型反应效率的提升。从金属离子、功能性配体以及其限域空腔三方面来详细阐述金属-有机笼状化合物在催化领域的研究进展,其中,金属-有机笼状化合物的金属离子催化性能主要表现在光致产H、光致产O_(2)和CO_(2)还原,其功能性配体能够调节不对称催化反应的对映选择能力,其限域空腔对光二聚体的形成起到了很好的催化效果,也能够对一般的有机反应起到明显的促进效果。最后提出了MOCs存在的问题并对其未来发展方向进行了展望。Metal-organic cages(MOCs)are self-assembled compounds with specific cavities by coordination between metal ions and organic ligands.Variable-valence metal ions,functional ligands and different structures cavities of MOCs provide a variety of possibilities for the catalytic active sites.This catalytic confinement effect of MOCs improves the efficiency of reactions of different types.Herein,The research progress of metal-organic cages in the field of catalysis was described in detail from three aspects:metal ions,functional ligands and confined cavities.Specifically,metal ions mainly exhibited their catalytic performances in photoinduced hydrogen/oxygen production and carbon dioxide reduction with functional ligands for regulating the enantioselective ability of asymmetric catalytic reactions and the confined cavities for the formation of photodimers as well as general organic reaction promotion.Meanwhile,the existing problems and future directions of MOCs were considered and discusses.
