OLEDs are currently the subject of an intense research effort due to their promise as devices for full color display application. Although considerable research efforts have been carried out to enhance the performance suitable for practical use. Balanced injection of holes and electrons into an emitting layer are considered a prerequisite for high luminous efficiency. We synthesized triphenylamine-phenothiazine copolymer containing 1,3,4-oxadialzole, which is substituted on triphenylamine moiety. From the polymer structure, we can expect that the polymer has balanced charge injection/transporting property. In this presentation, synthesis, optical, electrochemical and electroluminescent properties of the polymer will be discussed. |
