Abstract

The excited-state dynamics of cyanide-bridged trinuclear carbonyl rhenium(I) complexes with general formula of [Re]p-[Re]c[Re]p {[Re]c=[(−NC)ReI(CO)2(phen)(CN−)]; [Re]p=[−ReI(CO)2(L L)(La)], L L= diimine or diphosphine, La=triphenylphosphine or carbonyl ligand} and the monomeric peripheral control complexes have been elucidated through a study with ultrafast transient absorption spectroscopy. The time constants for the energy transfer between the MLCT excited states of the peripheral and central Re(I) chromophores (ca. 0.56–0.78 ps) are typical for other cyanide-bridged polynuclear transition metal complexes. The emissive excited states and the absorption transient have been characterized by nanosecond transient Raman spectroscopy.
