ABSTRACT:
The present invention provides organic light emitting devices (OLEDs) and materials with improved stability and efficiency when incorporated into an OLED. The materials include organometallic compounds having carbene atom/donor coordinated to a metal center. The compounds may be macrocyclic electrophosphors. The compounds may also include a macrocyclic ligand coordinated to a metal center.
