Spatially-doped charge transport layers

Abstract

Disclosed herein is an organic electronic device comprising a charge transport layer comprising a host charge transport material and a guest charge transport material, wherein the guest material is not homogeneously distributed in the host material and is spatially doped within the host material. The charge transport layer may be either a hole or electron transport layer and is useful in a variety of organic electronic devices.
