ORGANIC ELECTROLUMINESCENT ELEMENT, ORGANIC THIN FILM, AND TRIAMINE COMPOUNDS

摘要

The present invention provides a triamine compound represented by general formula (I): <CHEM> an organic luminescence device which comprises an organic layer and a pair of electrodes disposed on both sides of the organic layer wherein the organic layer at least contains a layer of a light emitting zone and a layer of a hole transporting zone which comprises a hole injecting layer containing the triamine compound and a hole transporting layer, and an organic thin film comprising two layers which are a layer containing a compound represented by general formula (I) and having a thickness of 5 nm to 5 mu m and a layer containing a compound represented by general formula (II): <CHEM> and having a thickness of 5 nm to 5 mu m. According to the present invention, an organic electroluminescence device which has little possibility of dielectric breakdown after storage for a long time and shows a remarkably high efficiency of light emission, an organic electroluminescence device which shows a remarkable stability of light emission after continuous use for a long time and has a long life, and an organic thin film which shows excellent hole injecting and transporting properties can be provided.
