- We report a new approach for photoinduced reduction of Cu²⁺ that will enrich the structural diversity of coordination complexes and be a valuable contributor to the development of Cu⁺/Cu⁰-based catalysts. To realize controlled Cu²⁺ reduction, coumarin as a triplet quencher of excited benzophenone was tethered to Cu(ii)–metal–organic polyhedra (MOPs). The photoinduced catalytic activity of the coumarin-MOPs was also examined in a Cu(i)-catalyzed azide–alkyne cycloaddition (CuAAC).
