NOVEL AROMATIC TERTIARY AMINES AND UTILIZATION THEREOF AS ORGANIC ELECTRONIC FUNCTIONAL MATERIAL

The invention provides an aromatic tertiary amine represented by the general formula (I) wherein X represents an aromatic divalent group which is 1,4-phenylene, a 1,4-naphthalenediyl or a 9,10-anthracenediyl group, and which may have substituents thereon; and R 1 to R 6 are each independently represent an aromatic monovalent group which may have substituents thereon, preferably a phenyl or a naphthyl group. The aromatic tertiary amine is useful as an organic electronic functional material, and can be suitably used as a hole injecting agent in a variety of electronic devices such as an electroluminescence element.
