CAS Number 1416881-53-2
4CzTPN, namely 2,3,5,6-tetrakis(carbazol-9-yl)-1,4-dicyanobenzene, is one of the three isomers of 4CzPN and 4CzIPN.
4CzTPN is normally used in thermally activated delayed fluorescence (TADF) device as green dopant materials. When it is compared with 4CzIPN, it has lower photoluminescence quantum efficiency and a shorter lived triplet lifetime due to the fact that 4CzIPN can widely disperse its highest occupied molecular orbital (HOMO) over the donor carbazolyl moieties.
