Highly Stable Copper(I)-Based Metal–Organic Framework Assembled with Resorcin[4]arene and Polyoxometalate for Efficient Heterogeneous Catalysis of Azide–Alkyne “Click” Reaction

A new highly stable copper­(I)-based metal–organic framework (MOF), namely, [CuI 4(SiW12O40)­(L)]·6H2O·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 char...

Description
Summary:A new highly stable copper­(I)-based metal–organic framework (MOF), namely, [CuI 4(SiW12O40)­(L)]·6H2O·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.
