Cz-DPS, bipolar host and blue dopant
Available in sublimed grade for TADF-OLED devices, 9,9'-(Sulfonylbis(4,1-phenylene))bis(9H-carbazole), CAS No. 733038-89-6, Sublimed ≥99.0%
Cz-DPS is consisted of two electron-donating carbazolyl moieties on both end of the molecule and one electron-withdrawing diphenylsulfone center unit. HOMO of 9,9'-(Sulfonylbis(4,1-phenylene))bis(9H-carbazole) is localized on the donor moieties extending to the diphenylsulfone unit, whereas LUMO of that is predominantly localized on the diphenylsulfone unit.
Cz-DPS is normally used as a bipolar host for TADF dopant or it could be used as a blue dopant itself.
