CAS Number 1141757-83-6
Tris-PCz has a tri-carbazole back-boned structure joined at the 3 and 6 positions. The highly-conjugated carbazoles makes Tris-PCz electron-rich, which is widely used as a hole-transport layer material in TADF-OLED devices.
Due to its electron-rich nature, Tris-PCz can form exciplexes with electron-deficient materials (such as B4PyPPM) in highly-efficient OLED devices with TADF characteristics.
Tris-PCz has a high triplet energy (ET = 2.7 eV), so it is also frequently used as an exciton block layer material to effectively prevent the excitons' energy from being transferred (to the donor or acceptor) to achieve high fluorescence quantum efficiency.
