  • Publication number: 20230357296
    Abstract: A compound having a first ligand LA of Formula I, is provided. In Formula I, Z is C or N; at least one of X1 to X5 is N, and the remainder are C; if X1 is N, then X5 is C; K is selected from the group consisting of a direct bond, O, S, N(R?), P(R?), B(R?), C(R?)(R?), and Si(R?)(R?); each R?, R?, RA and RB is a hydrogen or a General Substituent; LA is coordinated to a metal M; and Ring A coordinates to M through a metal carbene bond. Formulations, OLEDs, and consumer products containing the compound are also provided.

  • Patent number: 11201299
    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.
