Patent ID: 11616203

Abstract:
An organic light emitting device (OLED) that includes an anode, a cathode, and an organic layer disposed between the anode and the cathode. The organic layer includes a metal compound that comprises a ligand LA of Formula I, wherein the dashed lines represent coordination to a metal M. The metal M is selected from the groups consisting of Os, Ru, Ir, Rh, Pt, Pd, and Cu, and the metal is further coordinated to one or more ligand(s) LB, wherein the ligand(s) LB can be the same or different if more than one ligand LB is present. Optionally one or two of the ligand(s) LB can independently link to the ligand LA through one of R1 to R5. The invention is also directed to a consumer product that includes an OLED, and the OLED includes an organic layer that includes a metal compound that comprises a ligand LA of Formula I.
