ABSTRACT:
Organic electroluminescent device can be formed with multiple layers including an electrode, an emission layer, and a buffer layer. The emission layer includes a light emitting material. The buffer layer is disposed between and in electrical communication with the electrode and the emission layer and includes a triarylamine hole transport material and an electron acceptor material. The buffer layer optionally includes one or more of a) a polymeric binder, b) a color converting material, and c) light scattering particles. The buffer layer can also be formed using a polymeric hole transport material having a plurality of triarylamine moieties.
