Abstract: Organic electronic devices comprising a covalently bonded organic/inorganic composite layer. The composite layer may be formed by the reaction of a metal alkoxide with a charge transport compound having one or more hydroxyl groups. Examples of metal alkoxides that can be used include vanadium alkoxides, molybdenum alkoxides, titanium alkoxides, or silicon alkoxides. This composite layer can be used for any of the various charge conducting layers in an organic electronic device, including the hole injection layer.

Abstract: Novel iridium complexes containing phenylpyridine and pyridyl aza-benzo fused ligands are described. Iridium complexes containing aza-benzo fused ligands in which an aryl group is conjugated to the aza ring of the specific aza-dibenzofuran ring system results in the formation of yellow phosphorescent compounds with superior device stability and efficiency. These complexes are useful as light emitters when incorporated into OLEDs.
