4CzTPN-Ph, orange emitting material used in highly efficient TADF-OLED devices

Used to effectively prevent molecular interactions


4CzTPN-Ph, a well-known orange emitting material that is widely used in highly efficient TADF-OLED devices.

Comparing to 4CzTPN, the eight phenyl groups at 3,6-positions of carbazole moieties can further increase the electron-donating ability for 4CzTPN-Ph while at the same time greater steric hindrance is introduced. The increased steric hindrance can effectively prevent molecular interactions, i.e. the formation of the excimer.

With the donor-acceptor structure enabling the molecule with good two emission characteristics, 4CzTPN-Ph can also be used for both one and two-photon cellular fluorescence imaging as nanoparticles dispersed in water with good dispersibility, superior resistance against photodegradation and photobleaching and low cytotoxicity.
