DMAC-TRZ
DMAC-TRZ, 10-(4-(4,6-Diphenyl-1,3,5-triazin-2-yl)phenyl)-9,9-dimethyl-9,10-dihydroacridine, has a bipolar structure containing both 2,4,6-triphenyl-1,3,5-triazine (TRZ) as the electron-accepting and 9,9-dimethyl-9,10-dihydroacridine (DMAC) as the electron-donating moieties.
DMAC-TRZ is a well-known sky blue TADF emitter for both highly efficient doped and non-doped OLED devices, with high maximum external quantum efficiencies (EQE) over 20%. It shows not only high photoluminescence quantum yield (PLQY, ≥90%) in doped films but also high PLQY (83%) in neat films with low concentration quenching.
