PXZ-TRZ, dopant in highly efficient TADF-OLED devices

High-purity (>99.0%) green emitter

PXZ-TRZ, namely phenoxazine-2,4,6-triphenyl-1,3,5-triazine, has a bipolar structure with phenoxazine (PXZ) as an electron donor unit and 2,4,6-triphenyl-1,3,5-triazine (TRZ) as an electron acceptor unit.

PXZ-TRZ is a green emitter and is mainly used as a dopant or assistant dopant material in highly efficient TADF-OLED devices, but can also be used as a host or co-host material. The orientational packing order of a linear-shaped dopant such as PXZ-TRZ can be selectively controlled in a randomly oriented co-host matrix with mCBP by varying the temperature during deposition of the thin films.
