Abstract
We reported a controlled architecture growth of high density and ordered nanowire film of poly(3,4-ethylene dioxythiophene) (PEDOT) via Langmuir-Blodgett (LB) technique, and self-assembly performance of PEDOT nanowires at air/water interface was investigated in detail. The conducting film consisting of high density and ordered nanowires was transferred onto ITO substrate as a hole injection layer for organic light emitting diodes (OLEDs). The results showed that, compared to conventional PEDOT film, the improved performance of OLEDs was obtained after using ordered PEDOT nanowire layer as hole injection layer. It also indicated that compact arrangement and well-ordered structure of conducting channel was attributed to the improvement of OLED performance, leading to the increase of charged carrier mobility in hole injection layer and the recombination rate of electrons and holes in the electroluminescent layer.
