General description
- 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.
Application
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).
