Abstract An unprecedented three-dimensional supramolecular MOF, namely [Zn3(bpy)3 (SO4)4]·(Me2NH2)2·DMF·9H2O (1, where bpy = 4,4′-bipyridine, DMF = N,N′-dimethylformamide), has been efficaciously synthesized under the solvothermal reaction. A single-crystal structure determination showed that the wavelike [Zn3(bpy)(SO4)4] layers are pillared by pairs of bpy ligands to give a new 4,6-connected binodal self-penetrated network with overall (4264)(42687382) topology. 1 also has been fully identified characterized by thermogravimetric analysis, gas adsorption properties and so on. In addition, a new Cu(II)-MOF (cat1) was further prepared by postsynthetic exchange (PSE) synthetic approach based on compound 1, which is proved to be an active catalyst for the Friedel–Crafts reaction of indole with β-nitrostyrenes. The result from this work provides a new attempt to describe the crystallization of inorganic sulfate anion link to the organic functional group, and the functionalization-induced MOF gain insights for designing new functional MOF.

具有新拓扑结构的硫酸锌（II）基多孔骨架及其在 Friedel-Crafts 烷基化反应中的催化剂用途

摘要 一种前所未有的三维超分子 MOF，即 [Zn3(bpy)3 (SO4)4]·(Me2NH2)2·DMF·9H2O (1，其中 bpy = 4,4'-联吡啶，DMF = N,N'-二甲基甲酰胺），已在溶剂热反应下有效合成。单晶结构测定表明，波状 [Zn3(bpy)(SO4)4] 层由成对的 bpy 配体支撑，形成具有整体 (4264)(42687382) 的新的 4,6 连接双节点自渗透网络拓扑。1 还通过热重分析、气体吸附性能等进行了充分鉴定。此外，基于化合物1，通过合成后交换（PSE）合成方法进一步制备了一种新的Cu（II）-MOF（cat1），证明其是吲哚与β-硝基苯乙烯的Friedel-Crafts反应的活性催化剂.
