PXZ-DPS, ideal green emitter for TADF-OLED devices

High photo-luminescence quantum yields and purity (>99.0%)

10,10′-(sulfonylbis(4,1-phenylene))bis(10H-phenoxazine) (PXZ-DPS), possess a structure of a weak electron-accepting diphenylsulfone and strong electron-donating acridine moieties. It is used as a TADF green emitter or dopant, and has a small ΔEST of less than 0.1 eV, a short lifetime of less than 3.1 µs.

Like DMAC-DPS, PXZ-DPS has high photo-luminescence quantum yields (PLQY) in devices even with the change of host materials. It is an ideal candidate for applications in green TADF-OLED devices with biploar charge-transporting capability.
