生物功能是通过将单个生物分子模块组装成大的聚集体或高度复杂的结构而产生的。在超分子化学中也采用了类似的策略，从简单的组分组装具有高级功能的复杂和高度有序的结构。在这里，我们报告了一系列的金刚石超分子框架具有介孔腔，这是组装金属咪唑配位笼和各种阴离子。小组分（金属离子、胺、醛和阴离子）通过包括共价键、配价键和弱CHX（X=O、F和）氢键的多重相互作用组装成分级复合结构。中孔腔足够大，可以捕获有机染料分子、配位笼和维生素B（12）。该研究有望激发基于配位基序和无机离子的新型结晶超分子框架材料。
Biological function arises by the assembly of individual biomolecular modules into large aggregations or highly complex architectures. A similar strategy is adopted in supramolecular chemistry to assemble complex and highly ordered structures with advanced functions from simple components. Here we report a series of diamond-like supramolecular frameworks featuring mesoporous cavities, which are assembled from metal-imidazolate coordination cages and various anions. Small components (metal ions, amines, aldehydes, and anions) are assembled into the hierarchical complex structures through multiple interactions including covalent bonds, dative bonds, and weak CHX (X=O, F, and ) hydrogen bonds. The mesoporous cavities are large enough to trap organic dye molecules, coordination cages, and vitaminB(12). The study is expected to inspire new types of crystalline supramolecular framework materials based on coordination motifs and inorganic ions.
