    摘要: An aromatic amine derivative having a specific structure. An organic electroluminescence device which is composed of one or more organic thin film layers sandwiched between a cathode and an anode, wherein at least one of the organic thin film layers, especially a hole transporting layer, contains the aromatic amine derivative. The aromatic amine derivative has at least one substituted or unsubstituted dibenzofuran skeleton and at least one substituted or unsubstituted terphenylene skeleton. Because the molecules in the aromatic amine derivate hardly crystallize, organic electroluminescence devices improving their production yield and having prolonged lifetime are provided.
