Abstract
The present invention includes novel heterocyclic materials for use as blue phosphorescent materials in OLED devices. The materials are based on carbene and heterocyclic 5-membered ring linked ligands, which may be complexed to a transition metal via a metal-carbon (carbene) bond and a metal-nitrogen covalent bond. In one aspect, the present invention provides compounds comprising a ligand Lhaving the structure of Formula I:
