Abstract

The electroluminescent (EL) properties of a cross-linkable carbazole-terminated poly(benzyl ether) dendrimer, G₃-cbz DN, doped into a PVK:PBD host matrix with a double-layer device configuration are investigated. Different concentrations of the guest material can control device efficiency, related to chromaticity of white emission and the origin of excited-state complexes occurring between hole-transporting carbazole units (PVK or G₃-cbz DN) and electron-transporting oxadiazole (PBD). Two excited states (exciplex and electroplex) generated at the interfaces of PVK/G₃-cbz DN and PBD result in competitive emission, exhibiting a broad band in the EL spectra.
