ABSTRACT:
Some embodiments provide a compound represented by Formula 1:wherein R1, R2, R3, R6, R7, and R8are independently selected from the group consisting of H, optionally substituted C1-12alkyl, optionally substituted phenyl, optionally substituted carbazolyl, optionally substituted diphenylamine and optionally substituted diphenylaminophenyl; provided that: at least one of R1, R2, and R3is selected from optionally substituted carbazolyl, optionally substituted diphenylamine and optionally substituted diphenylaminophenyl and at least one of R6, R7, and R8is selected from optionally substituted carbazolyl, optionally substituted diphenylamine and optionally substituted diphenylaminophenyl; and R4and R5are independently selected from the group consisting of H, optionally substituted C1-12alkyl, optionally substituted phenyl, optionally substituted diphenylamine and optionally substituted diphenylaminophenyl. Other embodiments provide an organic light-emitting diode device comprising a compound of Formula I.
