DCzTRZ, full name 9,9'-(5-(4,6-Diphenyl-1,3,5-triazin-2-yl)-1,3-phenylene)bis(9H-carbazole), has a structure of two electron donating carbazole moieties attached to one of the phenyl rings of an electron deficient 1,3,5-triphenyltriazine unit.
Like TCzTRZ, DCzTRZ is used as a bipolar blue dopant material in highly efficient TADF-OLED devices. The only difference between DCzTRZ and TCzTRZ is that DCzTRZ is relatively blue shifted in absorption and emission, while TCzTRZ has one more carbazole unit.
As an electron acceptor, DCzTRZ can form exciplex with electron donor DMAC-DPS for green TADF-OLED devices with high photoluminescence quantum yield and high quantum efficiency.
