Product Details

T2T, host material for phosphorescent OLEDs and ETL material for TADF-OLEDs

High-purity (>99.0%) and available online for priority dispatch


2,4,6-tris(biphenyl-3-yl)-1,3,5-triazine (T2T) is a family member of triazine. It has one electron-withdrawing triazine core and three electron-rich biphenyl groups. It has been widely used as a host material for phosphorescent OLEDs and for .

Due to its electron-deficient nature, T2T and its derivatives are also used as acceptor materials to form exciplexes in blue-emission TADF devices.
