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, a carbazole based bipolar host material, can be used as an acceptor molecule for the fabrication of a photosensitizer. It can also be used in application such as phosphorescent organic light-emitting diodes (OLEDs).

• A bipolar host material for highly efficient blue phosphorescent OLEDs.
• TAPC:DPTPCz-based device showed a high EQE of 15.4%, which is the highest performance exciplex OLED up to date.
