Abstract
This article describes the synthesis and characterization of an organic–inorganic hybrid polyoxometalate functionalized by a short link with a tripodal N-based ligand and its copper complex. Upon visible light irradiation, the latter is able to store up to three reducing equivalents. The locus of the reduction is discussed based on physicochemical measurements and DFT calculations. In the presence of Togni’s reagent, this complex allows for the photocatalytic generation of CF 3 radicals, opening the road to valuable synthetic applications.
