5TCzBN is another sky-blue emitter from the cabzolyl benzonitrile (CBN) family that is used in TADF-OLED devices with great performance.

Acting as an encapsulation shell to the luminophore in 5TCzBN, tert-butyl units are believed to reduce the singlet–triplet splitting (ΔEST) of the compounds, which gives rise to a more efficient reverse intersystem crossing (RISC) process by effectively separating the neighbouring molecules.
