ABSTRACT:
An electroluminescent device comprises a light-emitting layer containing a light emitting phosphorescent material that contains an organometallic complex comprising iridium fully complexed with indole ligand groups or comprising Ir, Rh, Os, Ru, Pt, and Pd and an isoindole compound. The invention further comprises compositions of certain such complexes as well as a display or area lighting devices and a process for emitting light. The organometallic materials function as useful phosphorescent light emitting materials in electroluminescent devices.
