State Data

The nature of the lowest excited state of rhenium and copper complexes of dipyrido[3,2- a:2′ ,3′-c]phenazine (Dppz) has been determined using Resonance Raman, Time- Resolved Resonance Raman Spectroscopy and Spectroelectrochemistry. Comparison of spectroelectrochemical data and excited state data show that for the complexes studied no reduced ligand bands are observed in the excited state spectra thus the lowest excited states are all Ligand Centred in nature. The use of substituents at the 11 and/or 12 position of the ligand has no effect on the excited state ordering.
