Abstract:
Novel phosphorescent metal complexes containing ligands having the Formula I: bearing either a naphthalene or other fused heterocycle moieties such as benzofuran and benzothiophene useful as emitters in OLEDs and improve the device efficiency and the FWHM of the emission are disclosed.

Claim (Index 15):
An organic light emitting device (OLED) comprising:\n an anode; a cathode; and an organic layer, disposed between the anode and the cathode, comprising a compound comprising a ligand L A  of Formula I: wherein Ring B represents a five- or six-membered aromatic ring; wherein R 3  represents from none to the maximum number of substitutions; wherein X 1 , X 2 , X 3 , and X 4  are each independently a CR or N; wherein\n (1) at least two adjacent ones of X 1 , X 2 , X 3 , and X 4  are CR and fused into a five or six-membered aromatic ring, or \n (2) at least one of X 1 , X 2 , X 3 , and X 4  is nitrogen, or \n (3) both (1) and (2) are true; \n wherein\n (a) R 1  is CR 11 R 12 R 13  or join with R 2  to form into a ring; or \n (b) R 2  is not hydrogen, or \n (c) both (a) and (b) are true; \n wherein R, R 2 , R 3 , R 11 , R 12 , and R 13  are each independently selected from the group consisting of hydrogen, deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acid, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein any two substituents among R, R 2 , R 3 , R 11 , R 12 , and R 13  are optionally joined to form into a ring; wherein L A  is coordinated to a metal M; wherein L A  is optionally linked with other ligands to comprise a tridentate, tetradentate, pentadentate, or hexadentate ligand; and wherein M is optionally coordinated to other ligands.
