Abstract: A compound of the formula MLALB where ligand LA is of Formula I, and ligand LB is of Formula II below. M is selected from Os(II) or Ru(II), and the compound MLALB has a formal neutral charge; and rings A, B, C, D, E, and F are independently a 5-membered or 6-membered aromatic ring, and RA, RB, RC, RD, RE, and RF each independently represent mono to the maximum allowable substitution, or no substitution. L1, L2, L3, and L4 independently represent a single bond or an organic linking group; W1, W2, W3, and W4 are independently selected from carbon or nitrogen; Y1, Y2, Y3, and Y4 are independently selected from carbon or nitrogen; and Z1, Z2, and Z3 are independently selected from carbon or nitrogen, and at least one of Z1, Z2, and Z3 is nitrogen. An organic electroluminescent device that includes an anode, a cathode, and an organic layer comprising a compound of the formula MLALB where ligand LA is of Formula I, and ligand LB is of Formula II above. A consumer product comprising an organic light-emitting device (OLED) above.

Abstract: A compound comprising a tridentate ligand LA selected from Formula I. The ligand LA is complexed to a metal M. wherein Z1 and Z2 are independently C or N, wherein if Z1 is C, then Z2 is N, or if Z1 is N then Z2 is C; X1, X2, X3, and X4 are independently selected from CR1 or N, and R1 can be the same or different for each of X1, X2, X3, and X4; X5, X6, and X7 are independently selected from CR2 or N, and R2 can be the same or different for each of X5, X6, and X7; X8 is independently selected from CR3 or N; and Y is selected from CRY or N, and RY is selected from hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, cycloalkenyl, heteroalkenyl, aryl, heteroaryl, nitrile, and combinations thereof, or optionally, RY can form a ring with R3. An OLED that includes an anode, a cathode, and an organic layer disposed between the anode and the cathode. The organic layer will include a compound of Formula I, and a consumer product that includes the OLED.
