Photoactive ruthenium metal complexes are relevant luminescent DNA markers, but deciphering their local excited state dynamics in complex biochemical environments is challenging. Here the authors combine femtosecond and nanosecond pump-probe spectroscopy to elucidate the local hydration effects and 3MLCT relaxation dynamics of [Ru(phen)2(dppz)]2+ in two G-quadruplexes.
