title: Electron injection barrier reduction for organic light-emitting devices by quinacridone derivatives.
abstract: Water/alcohol-soluble quinacridone derivatives have been synthesized and utilized as an electron injection layer in organic light-emitting diodes. Initial results are very promising, as a device with a layer of Na(+)QHSO(3)(-) adjacent to an Al cathode exhibited a luminance efficiency (1.65 cd A(-1)) that was significantly enhanced relative to the efficiency (0.85 cd A(-1)) of a control device with an unstable, lower work function Ba/Al cathode.
