Abstract
Some embodiments provide a compound represented by Formula 2B: wherein Ph1 and Ph2 are independently optionally substituted 1,4-interphenylene or optionally substituted 1,3-interphenylene, y may be 0 or 1, and z may be 0 or 1. In some embodiments, R9 and R10 are independently H, C1-3 alkyl, or C1-3 perfluoroalkyl. In some embodiments, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, and R22 are independently selected from the group consisting of H, C1-12 alkyl, C1-6F1-13 fluoroalkyl, and optionally substituted phenyl. Other embodiments provide an organic light-emitting diode device comprising a compound of Formula 2B.
