Polyoxometalates (POMs) are redox and photoactive metal oxide clusters with various potential applications in next generation nanotechnologies. Although the vast majority of POMs absorb only in the UV region, we present a new strategy to photoactivate the metal oxide shell under visible-light irradiation. By grafting a variety of phosphonate moieties to the POM core, we show that it is possible to selectively tune the photoactivity of the POM via rational modification of the frontier orbital energies.
