High-purity green emitter, Phenoxazine-2,4,6-triphenyl-1,3,5-triazine, CAS No. 1411910-25-2, Sublimed ≥99.0%
PXZ-TRZ 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.
