Temperature-Dependent Photophysical, Photochemical and Redox Properties of Novel Complexes (CO)2CpRu-Ru(Ln)-RuCp(CO)2 and (CO)2CpRu-Ru(Ln)-SnPh3 [Ln = (CO)2(N,N′-diisopropyl-1,4-diaza-1,3-butadiene)]
The photophysical, photochemical and redox properties of the title complexes were investigated. Resonance Raman measurements revealed the lowest-energy electronic transition to possess σ→π* character. At low temperatures, long-lived near-IR emission was observed. Irradiation in solution results in homolytic splitting of a Ru-Ru bond as the primary step, followed by secondary reactions of the radical fragments depending on the experimental conditions. (Spectro)electrochemical investigations of the title species proved that the axial [RuCp(CO)2] groups exert a stabilising influence on the corresponding radical cations, while destabilising the corresponding radical anions, compared to the redox behaviour of other ruthenium complexes of this type..
