O comportamento fotoquímico dos complexos pentaaminas de rutênio(II) com ligantes pi insaturados

A general overview on the photochemical behaviour of [Ru(NH3)(5)L](2+) complexes (where L is a pi ligand) is presented. The proposed mechanisms and techniques employed for the study of these reactions are discussed. Emphasis is made on the mechanisms that allow the identification of the reactive excited state of the [Ru(NH3)(5)py](2+) complex.
