Abstract

Abstract : Ultrafast spectroscopic studies on the excited state interplay in trifluoromethyl-substituted iridium(iii ) complexes. Abstract : Time-resolved spectroscopy was exploited to gain new insights into the nature and dynamics of charge transfer excited states of bis-cyclometalated Ir(iii ) complexes. We showed that its dynamics is strongly influenced by the nature of the diimine ligand due to the existence of a ligand–ligand charge transfer process in the picosecond timescale. All the results are supported by DFT/TD-DFT calculations and spectroelectrochemistry.
