Abstract
The efficiency of light-emitting diodes (LEDs) based on poly[(9,9-dioctylfluorenyl-2,7-diyl)- alt-1,4-benzo- { 2, 1 -3 } -thiadiazole)],
F8BT, is optimized upon simultaneous doping with a hole and an electron trapping molecule, namely,
N, N -Bis(3-methylphenyl)-N, N -diphenylbenzidine and 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole,
respectively. It is shown that, for devices with poly(3,4-ethylene dioxythiophene) doped with polystyrene
sulfonic acid as hole-injection layer material and magnesium cathodes, the efficiency is nearly doubled
(from ca. 2.5 to 3.7 cd/A) upon doping with ca. 0.34% by weight of both compounds.
