In addition to hole transport, diphenylamino-end-capped oligofluorenyithiophenes 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 m2 with a luminance efficiency up to 5.3 and 1.0 cd A-1, respectively.
