Novel heteroleptic iridium complexes are described. These iridium compounds contain alkyl substituted phenylpyridine ligands, which provide these compounds with beneficial properties when the iridium complexes are incorporated into OLED devices.
Novel phosphorescent heteroleptic iridium complexes with phenylpyridine and dibenzo-containing ligands are provided. Alkyl substitution at specific positions on the ligands gives rise to compounds with improved OLED properties, including saturated green emission.
