Confinement of a metal complex is a promising way to induce reactivity modulation and selectivity. Combining this principle with the properties of N-heterocyclic carbenes (NHC) used as ligands is therefore of great interest. NHCs metal complexes have been encapsulated in polymeric structures (metal-organic frameworks, metal organic polymers and porous organic polymers), and in molecular containers (capsules, cages or cavitands). This confinement induced reactivity change, on and off switching of reactions, substrate selection, stereoselectivity, regioselectivity, and product distribution variation. The syntheses and the influence of confinement on reactivity will be discussed in this Minireview.
将金属配合物限制在一定空间内是一种很有前景的诱导反应活性和选择性的方法。因此，将这一原理与作为配体的 N-杂环卡宾（NHC）的特性结合起来具有重要意义。NHCs 金属配合物已被封装在聚合结构（金属有机框架、金属有机聚合物和多孔有机聚合物）和分子容器（胶囊、笼状或主体）中。这种限制诱导的反应活性变化、反应的开/关切换、底物选择、立体选择性、区域选择性和产物分布变化。本综述将讨论受限条件对反应活性的影响。
