A novel polymer supported [poly (styrene‐co‐maleic imide) (SMI)]Cu(I) nano‐particles was prepared via in situ reaction of 4‐amino‐5‐methyl‐4 H ‐1,2,4‐triazole‐3‐thione with [poly (styrene‐co‐maleic anhydride)] (SMA) along with immobilization of CuI. These nano‐particles were fully characterized by using scanning electron microscopy (SEM), energy dispersive spectroscopy analysis, Xray (EDAX), inductively coupled plasma (ICP) analysis, 1 H NMR and FT‐IR techniques. Moreover, the structural and electronic features of metal–ligand interactions in the complex model of polymer‐supported copper nanocatalyst were assessed using density functional theory calculations. The catalytic activity of these supported Cu(I) nonoparticles was examined in one of the classiest name reaction so–called “click reaction” which is coined K. B Sharpless for the regioselective synthesis of 1,2,3‐triazole derivatives using a multicomponent reaction (MCR) involving benzyl halides, sodium azide and terminal alkynes in water as a green solvent. This heterogeneous catalyst showed excellent catalytic activity and was separated by simple filtration and was used at least in five consecutive runs without a significant decrease in its activity.
