Abstract
Electro luminescent metal, e.g. Ir, complexes are disclosed. The metal complexes comprise at least one ligand L1 and at least one ligand L2, wherein ligand L1 is a 2-phenylpyridine ligand (I), comprising a phenyl ring (A) and a pyridine ring (B). The integers 2 to 9 denote positions in which substitutions can be made, and by the use of different substituents, e.g. 2,4-difluoro and 7-N(CH3)2, the emission wavelength of the complex may be tuned. The ligand L2 may e.g. be a compound of the following formula (II).
