    摘要： A compound including a first ligand L A of Formula I

    is disclosed. In the structure of Formula I, one of L 1 and L 2 is C, and the other is N; Y 1 to Y 14 are each C or N; at least two adjacent Y 7 , Y 8 , Y 9 , and Y 10 are carbon atoms that are fused to a structure of Formula II

    Z 1 and Z 2 are each O, S, Se, NR, CRR', or SiRR'; and each R, R', R A , R B , R C , and R D is hydrogen or a substituent; and any two substituents may be joined or fused together to form a ring. In the compound, L A is complexed to a metal M by L 1 and L 2 , and M has an atomic weight greater than 40. Organic light emitting devices and consumer products containing the compounds are also disclosed.
