Ambipolar Diphenylamino End-Capped Oligofluorenylthiophenes as Excellent Electron-Transporting Emitters

In addition to hole transport, diphenylamino-end-capped oligofluorenylthiophenes can exhibit efficient electron transport, in which the oligothiophene central core acts as an excellent electron-transporting moiety. The highly efficient undoped multilayer OLEDs using OF(2)TTP - NPh and OF(2)QTP-NPh a...

Zusammenfassung:In addition to hole transport, diphenylamino-end-capped oligofluorenylthiophenes can exhibit efficient electron transport, in which the oligothiophene central core acts as an excellent electron-transporting moiety. The highly efficient undoped multilayer OLEDs using OF(2)TTP - NPh and OF(2)QTP-NPh as an electron-transporting emitter exhibited a maximum luminance of 19 800 and 11 800 cd m-2 with a luminance efficiency up to 5.3 and 1.0 cd A-1, respectively.
