3-(4,6-Diphenyl-1,3,5-triazin-2-yl)-9-phenyl-9H-carbazole (DPTPCz) is an isomer to Cab-Ph-TRZ with triazine as electron-deficient and carbazole as electron-rich moieties. The difference between them is that for DPTPCz, triazine is directly attached to the carbazole unit while there is a phenyl spacer between the trazine and carbazole units for Cab-Ph-TRZ.

DPTPCz is used as a phosphorescent host material for blue, green and red light-emitting diodes. The bipolar host can achieve balanced charge injection/transport in phosphorescent organic light emitting diodes (PhOLEDs). Nearly 100% triplet harvesting in conventional fluorophor-based organic light-emitting devices is realized through energy transfer from TAPC:DPTPCz exciplex with C545T-doped device. The device showed a maximum current efficiency of 44.0 cd A^-1, a maximum power efficiency of 46.1 lm W^-1, and a maximum external quantum efficiency of 14.5% [3]
