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.
