Disclosed is a metal complex having a partial structure represented by the following Formula (I-0) or a tautomer thereof: formula (I-0) Cy is a 5 to 7 membered heterocyclic ring, preferably a 6-membered ring, which may be aromatic, non aromaticor partially aromaticand which coordinates to the metal atom through a carbon atom; A is a nitrogen atom a is an integer equal or superior to 1; D is an electron donor group; and b is an integer equal or superior to 1.

iridium(III) complexes have been widely studied, only correlations between oxidation potential EOX and Hammett constant σ, and between the redox gap (ΔEREDOX = EOX − ERED) and emission or absorption wavelength (λabs, λem) have been reported. We present now a quantitative model based on Hammett parameters that rationalizes the effect of the substituents on the properties of cyclometalated iridium(III) complexes
