摘要： A compound having a structure of Formula I: is described. In the structure of Formula I, RA, RB, and RC are each independently 5 or 6 membered aryl or heteroaryl rings; R1, R2, R3, 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; X1 is B, C, N, O, S or Se; and X2-X7 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.

摘要： A compound having the structure of Formula I is disclosed. In the structure of Formula I, each of R1, R2, and R3 is independently a hydrogen, a non-fused aryl group having one meta-substituent, or a non-fused heteroaryl six-membered ring having one or more meta-substituents; each meta-substituent is a non-fused aryl or non-fused heteroaryl six-membered ring optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups; and at least one of R1, R2, and R3 is a non-fused aryl having one meta-substituent or a heteroaryl six-membered ring having at least one meta-substituent, wherein each meta-substituent is a non-fused aryl or non-fused heteroaryl group further substituted with a chain of at least two non-fused aryl or non-fused heteroaryl groups. The compounds may be useful in phosphorescent organic light emitting devices.
