Abstract: This invention relates to the development of heterocyclic materials for use as blue phosphorescent materials in OLED devices. The materials are based on a pair of 5-membered aromatic or psuedoaromatic rings bonded to one another and complexed to a transition metal. The materials were determined computationally to have appropriate triplet energies for use as blue emitters and to possess sufficient chemical stability for use in devices.

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 LA having the structure of Formula I:

Abstract: The present invention includes novel platinum complexes with tridentate ligands forming dimeric structures that are calculated to have blue emission. The ligand backbone and pendant donor rings can be altered to give different emission maxima. The present invention also includes various pendant donor rings and multiple different ligand backbones. Such complexes are suitable for use as an emitter in organic light emitting devices.

Abstract: 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.
