Abstract
The new complex [Ru(dppz)(4AP)4]2+ (1, in which dppz = dipyrido[3,2-a:2,3-c]phenazine and 4AP = 4-aminopyridine) has been synthesized, characterized and its photophysical and photochemical properties have been studied by combining spectroscopic and computational [DFT and time-dependent (TD) DFT] methods. Upon irradiation in aqueous solution, complex 1 selectively photoreleases one 4AP ligand and subsequently coordinates a water molecule to form [Ru(dppz)(4AP)3(OH2)]2+
