auxiliary ligand, and their fluoride adducts were prepared and characterized. While the PL spectra of 2 and 3 exhibit very weak emission in solution, the addition of fluoride turned on (C∧N)2Ir-centered phosphorescence (λem 527 nm for 2 and 617 nm for 3). Experimental and DFT calculations suggest that the weak emission is ascribable to a photoinduced electron transfer from the MLCT state of the (C∧N)2Ir
