A new highly stable copper(I)-based metal-organic framework (MOF), namely, [Cu(SiWO)(L)]·6HO·2DMF (1), was synthesized by incorporating Keggin-type polyoxometalate (POM) anions and a functionalized wheel-like resorcin[4]arene-based ligand (L) under sovothermal condition. 1 exhibits a charming 3D supramolecular architecture sandwiched by the POM anions. Noticeably, 1 has exceptional chemical stability, especially in organic solvents or aqueous solutions with a wide range of pH values. Considering the catalytically active Cu(I) sites in 1, the azide-alkyne cycloaddition (AAC) reaction was studied by employing 1 as the heterogeneous catalyst. Most strikingly, 1 exhibits excellent catalytic activity as well as recyclability for the AAC reaction.
一种新的高稳定铜（I）基金属有机骨架（MOF），即[Cu（SiWO）（L）]·6HO·2DMF（1），是通过在溶剂热条件下引入 Keggin 型多金属氧酸盐（POM）阴离子和功能化轮状均苯四酚基配体（L）合成的。1 表现出迷人的 3D 超分子结构，由 POM 阴离子夹在中间。值得注意的是，1 具有异常的化学稳定性，特别是在有机溶剂或具有广泛 pH 值的水溶液中。考虑到 1 中催化活性的 Cu（I）位点，我们研究了 1 作为非均相催化剂的叠氮-炔基环加成（AAC）反应。最引人注目的是，1 对 AAC 反应表现出优异的催化活性和可回收性。
