4CzTPN-Me, TADF material for highly efficient delayed fluorescence devices
Potentially used for high efficiency and low-cost solar energy generation
2,3,5,6-tetrakis(3,6-dimethylcarbazol-9-yl)-1,4-dicyanobenzene (4CzTPN-Me) is the methylated derivative of 4CzTPN and it is sterically hindered due to the four bulky electron-donating carbazolyl groups. It belongs to the family member of carbazolyl dicyanobenzene derivatives (CDCB derivatives) which are among the first developed TADF materials for the application of 3rd generation of highly efficient delayed fluorescence devices.
Due to its sterically twisted structure and rather unique charge transfer characteristics, 4CzTPN-Me could be potentially used for high efficiency and low-cost solar energy generation, gaining almost zero re-absorption losses in luminescent solar concentrator (LSC).
