cyclopentadienylIrL2 unit is suggested to be a possible route for the quenching of the anthrylene fluorescence. The oxidation of 3 and 4 by [bis(trifluoroacetoxy)iodo]benzene (PIFA) and thallium(III) trifluoroacetate (TTFA), respectively, produces the radical cations 3+ and 4+, which, on the base of their EPR spectra, are described as average-valence [Ir+1.5, Ir+1.5] species.
