Abstract
It is shown that the excited states of Ru(TAP) 2+ 3 (TAP ≡ 1,4,5,8-tetraazaphenanthrene) and Ru(TAPMe 2) 2+ 3 (TAPMe 2 ≡ 2,7-dimethyl-1,4,5,8-tetraazaphenanthrene) are too weak reductants to be oxidized at SnO 2 electrodes. On the other hand, in the presence of a reducing agent such as hydroquinone, the photo-generated reduced complexes are able to inject electrons into the SnO 2 conduction band. The good agreement between the Stern-Volmer constants obtained by luminescence quenching and by photoelectrochemistry confirms this electron transfer process.
