Multi-component metal-organic frameworks (MOFs) with precisely controlled pore environments are highly desired owing to their potential applications in gas adsorption, separation, cooperative catalysis, and biomimetics. A series of multi-component MOFs, namely PCN-900(RE), were constructed from a combination of tetratopic porphyrinic linkers, linear linkers, and rare-earth hexanuclear clusters (RE ) under the guidance of thermodynamics. These MOFs exhibit high surface areas (up to 2523 cm g ) and unlimited tunability by modification of metal nodes and/or linker components. Post-synthetic exchange of linear linkers and metalation of two organic linkers were realized, allowing the incorporation of a wide range of functional moieties. Two different metal sites were sequentially placed on the linear linker and the tetratopic porphyrinic linker, respectively, giving rise to an ideal platform for heterogeneous catalysis.
具有精确可控孔环境的多组分金属有机框架材料（MOFs）因其在气体吸附、分离、协同催化和仿生学等方面的潜在应用而备受关注。在热力学指导下，通过四齿卟啉连接体、线性连接体和稀土六核簇（RE）的组合构建了一系列多组分MOF，即PCN-900(RE)。这些MOF具有高比表面积（高达2523 cm g ），并且通过修饰金属节点和/或连接体组分可实现无限可调性。实现了线性连接体的后合成交换和两种有机连接体的金属化，从而能够引入多种功能基团。分别在线性连接体和四齿卟啉连接体上依次引入两种不同的金属位点，为多相催化提供了理想的平台。
