  Organometallic compounds comprising an imidazole carbene ligand having a N-containing ring fused to the imidazole ring are provided. In particular, the N-containing ring fused to the imidazole ring may contain one nitrogen atom or more than one nitrogen atom. These compounds may demonstrate high photoluminescent (PL) efficiency, Gaussian emission spectra, and/or short excited state lifetimes. These materials may be especially useful as blue phosphorescent emitters. The compounds are of formula I wherein A is a 5-membered or 6-membered carbocyclic or heterocyclic ring; wherein R2 and RA may represent mono, di, tri or tetra substitutions; wherein each of R1, R2 and RA is independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein two adjacent substituents of R2 and RA are optionally joined to form a fused ring; wherein each of X1, X2, X3 and X4 are independently selected from the group consisting of C and N; wherein at least two of X1, X2, X3 and X4 are N; wherein the ligand L is coordinated to a metal M having an atomic number greater than 40; and wherein the bidentate ligand may be linked with other ligands to comprise a tridentate, tetradentate, pentadentate or hexadentate ligand.
