Abstract:
Novel phosphorescent heteroleptic iridium complexes with substituted phenylquinoline ligands are provided. The alkyl substitution on the phenylquinoline ligands together with larger alkyl substituents on the acetylacetone-derived ligands produces complexes with improved properties that are useful when incorporated into OLED devices.
