Abstract

The photophysics of the fac-[Re(Cl)(CO)₃(CO₂Et-dppz)] (CO₂Et-dppz = dipyrido[3,2a:2′,3′c]phenazine-11- carboxylic ethyl ester) was studied with picosecond time-resolved infrared (ps-TRIR) spectroscopy in metal carbonyl (2100-1800cm^-1) and organic ester (1800-1600cm^-1) spectral regions. The ps-TRIR spectra in both regions give evidence for the formation of a metal-to-ligand charge transfer (MLCT) excited state. The magnitude of ν(C≡O) shift in the metal carbonyl region of the excited state relative to those of the ground state allows the excited state to be described more precisely as a dπ(Re) → π* (phenazine) ³MLCT state.
