We report a simple methodology for the stabilization of Cu2O nanoparticles of size 2-4 nm on the polar pore surface of a 2D metal-organic framework, {[Zn(Himdc)(bipy)(0.5)]center dot DMF} (1). For the first time, a Cu2O@1a (1a: desolvated 1) composite has been utilized as a recyclable catalyst for the Huisgen 1,3-dipolar cycloaddition reaction of terminal alkynes and aliphatic/aromatic azides for the synthesis of 1,2,3-triazoles.
