Zusammenfassung:A compound having a structure of Formula I: is described. In the structure of Formula I, R A , R B , and R C are each independently 5 or 6 membered aryl or heteroaryl rings; R 1 , R 2 , R 3 , and A are selected from a variety of substituents, including being joined or fused to form a ring; A is optionally bonded to at least one benzo or azabenzo ring to form fused rings; X 1 is B, C, N, O, S or Se; and X 2 -X 7 are independently B, C or N. Formulations and devices, such as an OLEDs, that include the compound containing a structure of Formula I are also described.
