title: "Click-and-click"--hybridised 1,2,3-triazoles supported Cu(I) coordination polymers for azide-alkyne cycloaddition.
abstract: Two novel pyridyl and thioether hybridised 1,2,3-triazole ligands 1-(2-picolyl)-4-(2-(methylthio)-pyridine)-1H-1,2,3-triazole (L1) and 1-(4-picolyl)-4-(2-(methylthio)-pyridine)-1H-1,2,3-triazole (L2) were prepared from CuAAC click reactions. Reactions of CuI with the ligands L1 and L2 yielded two one-dimensional coordination polymers [Cu6I6(L1)2]n (1) and [Cu2I2(L2)2]n (2). Single-crystal X-ray diffraction reveals that 1 and 2 are polymeric with [Cu6I6] and [Cu2I2] respectively as building blocks. Both ligands (L1 and L2) and complexes (1 and 2) are photoluminescence active. Complexes 1 and 2 are also catalytically active towards azide-alkyne cycloaddition reactions.
