A TADF orange emitter

Highly efficient TADF materials for OLEDs, Photosynthesis, Time-Resolved Luminescence Imaging and Sensing


4CzIPN-Ph, 2,4,5,6-tetrakis(3,6-diphenylcarbazol-9-yl)-1,3-dicyanobenzene, has the structure origin of 4CzIPN with 8 phenyl substituents at 3,6-positions of carbazolyl moieties. Due to the steric conformational effects, the phenyl rings are relatively decoupled from the core of the molecule in 4CzIPN-Ph.

Wavefunctions suggests a partial delocalization of the hole electronic density into the outer phenyl rings, thus enhancing its charge transfer character with reduces ΔEST. Devices using single DMAC-DPS: 4CzTPN-Ph emission layer achieved a maximum external quantum efficiency of 13.4%, maximum power efficiency of 38.3 lm W-1 and current-insensitive Commission Internationale de I'Eclairage (CIE) coordinates of (0.29, 0.39).

4CzIPN-Ph, 4CzPN-Ph and 4CzTPN-Ph are isomers with two nitrile (CN) groups sitting at meta-, ortho- and para- positions of the benzene ring respectively.
