Abstract

Abstract : A combination of UV-Vis, resonance Raman spectroscopy and electrochemistry is employed to reveal the nature of a side product when using heteroleptic Cu(i )-photosensitizers for photocatalytic hydrogen production. Abstract : A combination of UV-Vis and resonance Raman spectroscopy in conjunction with electrochemistry is employed to reveal the nature of a side product formed when using heteroleptic Cu(i )-photosensitizers [(P^P)Cu(N^N)] + for photocatalytic hydrogen generation. It is shown that homoleptic [Cu(N^N)2 ] + complexes are formed under oxidative conditions confirming a proposed deactivation pathway.
