9-(4-(4,6-Diphenyl-1,3,5-triazin-2-yl)phenyl)-9H -carbazole (Cab-Ph-TRZ) is ambipolar in nature, with triazine as electron-deficient and carbazole as electron-rich moieties.
Cab-Ph-TRZ is typically used as a phosphorescent host material for green and red light-emitting diodes. Compared to CBP - 4,4′-Bis(N-carbazolyl)-1,1′-biphenyl as a host material, Cab-Ph-TRZ shows higher power efficiencies with lower driving voltage, thanks to its bipolar nature.
