Self-Assembled of Conducting Polymeric Nanoparticles and Its Application for OLED Hole Injection Layer

摘要：

We reported a controlled architecture growth of high density and ordered polymeric nanoparticle film of poly (3,4-ethylene dioxythiophene) (PEDOT) via Langmuir-Blodgett (LB) technique, and self-assembled performance of PEDOT nanoparticles at air/water interface was investigated in detail.The conducting film consisting of high density and ordered nanoparticles 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 nanoparticle 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.
