Light Emitting Molecular Devices Based on Transition Metals

Multicomponent systems have been designed, which are able to perform defined functions related to light emission and quenching. The desired function can be switched ON/OFF by the operator through a chemical input, either a change of pH or a variation of the redox potential. Transition metals (e.g. Ni(II), Cu(II)) are key constituents within the considered systems, playing a distinctive architectural role and favouring electron transfer processes
