Patent ID: 11716900

Abstract:
A compound having a stoichiometry formula of BiL3, where each L has a formula of where each Z1 and Z2 is O, S, NR, or PR; Z3 is C; Z1, Z2, the single dashed line represent a bond to Bi; and n is an integer. In these structures, LA can be aryl or heteroaryl, which can be substituted. Substituents RL, R, LC, and RLC can be selected from a variety of substituents. In the first formula, at least one of the following is true: (1) LA includes a 5-membered ring; (2) LA includes a condensed ring system of at least three rings; (3) at least one RL is a non-fused aryl or heteroaryl moiety; or (4) n is at least 2 with two different RL's and LA-(RL)n is asymmetrical. Organic light emitting devices, consumer products, formulations, and chemical structures containing the compounds are also disclosed.
