Abstract
This invention discloses metal complexes containing a ligand comprising a carborane moiety. Organic electroluminescent devices comprising these metal complexes containing a carborane moiety in the light-emitting layer showed desired properties in term of external quantum efficiency (EQE), device lifetime (LT), and color purity as measured by CIE.
