Coordination polymers, commonly known as infinite crystalline lattices, are versatile networks and have diverse potential applications in the fields of gas storage, molecular separation, catalysis, optics, and drug delivery, among other areas. Secondary building blocks, mainly incorporating rigid polydentate organic linkers and metal ions or clusters, are commonly employed to construct coordination polymers. Recently, novel building blocks such as coordination polyhedra have been utilized as metal nodes to fabricate coordination polymers. Benefiting from the rigid porous structure of the coordination polyhedron, prefabricated designer “pores” can be incorporated in this type of coordinate polymer. In this Account, coordination polymers built by pyrogallol[4]arene-assembled metal–organic nanocapsules are summarized. This class of metal–organic nanocapsule possesses the following advantages that make them excellent candidates in the construction of coordination polymers: (i) Various geometrical shapes with different volumes of the inner cavities can be obtained from these capsules. Among them, the two main categories illustrated are dimeric and hexameric capsules, which comprise two and six pyrogallol[4]arenes units, respectively. (ii) A wide range of possible metal ions ranging from main group metals to transition metals and even lanthanides have been demonstrated to seam the capsules. Therefore, these coordination polymers can be endowed with fascinating functionalities such as magnetism, semiconductivity, luminescence, and radioactivity. (iii) Up to 24 metal ions have been successfully embedded on the surface of the nanocapsule, each a potential reaction site in the construction of coordination polymers, opening up pathways for the formation of multidimensional frameworks.

由邻苯三酚[4]芳烃组装的金属-有机纳米胶囊构建的配位聚合物
配位聚合物，通常称为无限晶格，是多功能网络，在气体储存、分子分离、催化、光学和药物输送等领域具有多种潜在应用。二级结构单元，主要结合刚性多齿有机接头和金属离子或簇，通常用于构建配位聚合物。最近，诸如配位多面体之类的新型构件已被用作金属节点来制造配位聚合物。受益于配位多面体的刚性多孔结构，预制的设计师“孔”可以加入这种类型的配位聚合物中。在这篇文章中，总结了由连苯三酚[4]芳烃组装的金属-有机纳米胶囊构建的配位聚合物。这类金属有机纳米胶囊具有以下优点，使其成为构建配位聚合物的绝佳候选者：（i）可以从这些胶囊中获得具有不同内腔体积的各种几何形状。其中，所示的两个主要类别是二聚体和六聚体胶囊，它们分别包含两个和六个连苯三酚 [4] 芳烃单元。(ii) 从主族金属到过渡金属甚至镧系元素的各种可能的金属离子已被证明可以缝合胶囊。因此，这些配位聚合物可以被赋予迷人的功能，如磁性、半导体、发光和放射性。(iii) 多达 24 个金属离子已成功嵌入纳米胶囊表面，
