Abstract
A compound containing a partial structure of Formula I: is provided. In the structure of Formula I, M is a metal with an atomic number of at least 40; RA, RB, and RC are each independently 5 or 6 membered aryl or heteroaryl rings; R1, R2, R3, and A are each independently selected from a variety of substituents and combinations thereof; A is optionally bonded to RA or RC to form a fused ring; X1 is B, C, N, O, S or Se; X2-X7 are independently B, C or N; and Y1-Y2 are independently C or N. Formulations and devices, such as an OLEDs, that include the compound containing a structure of Formula I are also described.
