Three thiacalix[4]arene-based Cu(i) coordination polymers: catalytic activities for azide–alkyne cycloaddition reactions and luminescence properties

Author affiliations

Abstract

Three new coordination polymers, [Cu2(CN)(L)(OCH3)]·CH3OH·3H2O (1), [Cu3(Br)3(L)] (2) and [Cu(I)(L)]·1.5H2O (3), have been solvothermally prepared by reacting L (5,11,17,23-tetra-tert-butyl-25,26,27,28-tetra[(3-pyridylmethyl)oxy]-2,8,14,20-tetrathiacalix[4]arene) with Cu(I) halide. 1 and 2 exhibit layers. 3 displays a chain, a supramolecular layer constructed by hydrogen bonds. The performance of 1–3 was examined as heterogeneous catalysts for azide–alkyne cycloaddition reactions. Most strikingly, 1 and 2 show predominant efficiency with high regioselectivity and excellent recyclability. Remarkably, solids 1–3 all have luminescence characteristics under irradiation with a UV lamp.
