  • Publication number: 20190135841
    Abstract: A compound that includes a ligand LA of Formula I, Formula II, or Formula III, and the ligand LA is coordinated to a metal M. Ring A is a 5-membered, or 6-membered, aromatic ring, and Ring B a 5-membered, or 6-membered, carboxylic or heterocyclic ring. Y1, Y2, and Y3 are independently selected from the group consisting of C, N, and B, and forms an aromatic BN ring; wherein one of Y1, Y2, and Y3 is C, one of Y1, Y2, and Y3 is N, and one of Y1, Y2, and Y3 is B, and the B and N are adjacent ring atoms; and Z1 and Z2 are independently selected from the group consisting of C and N. The compounds can be used as phosphorescent dopant emitters in OLEDs. An OLED that includes an organic layer that includes a compound with a ligand LA of Formula I, Formula II, or Formula III, and a consumer product that includes the OLED.
