摘要： 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.

摘要： The present invention includes novel heterocyclic materials for use as blue phosphorescent materials in OLED devices. The novel materials include two fused 5-membered aromatic or pseudoaromatic rings, which are bonded with 6 membered aromatic rings to serve as chelation ligands for a transition metal. The novel materials were determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.
