We report efficient carrier injection characteristics in liquid organic light-emitting diodes (OLEDs). The use of a liquid carbazole substituted with a poly(ethylene oxide) (PEO) chain provided a substantial improvement in carrier injection compared to devices constructed with carbazoles without PEO units. The external electroluminescence quantum efficiency (φ _EL) of an OLED with the liquid carbazole as an emitting layer resulted in φ _EL = 0.75%, 25 times higher φEL than that of our previous liquid OLED without electrolyte.
