Provided are a long-lifetime organic electroluminescence device which can be fabricated in an improved yield owing to suppressed crystallization of molecules, and an aromatic amine derivative that realizes the device, i.e., a novel aromatic amine derivative having a specific structure. Specifically provided are an organic electroluminescence device, including an organic thin film layer formed of one or more layers including at least a light emitting layer, the organic thin film layer being interposed between a cathode and an anode, and an aromatic amine derivative for at least one layer of the organic thin film layer, in particular, a hole transporting layer, the derivative having at least one such structure that a substituent in which two or more specific heterocycles are linked to each other, in particular, a substituent in which two or more specific heterocycles are linked through an aryl group is bonded to an amine through an aryl group.
提供了一种长寿命有机电致发光器件,由于分子的结晶被抑制,可以提高制造产量,以及实现该器件的芳香胺衍生物,即具有特定结构的新型芳香胺衍生物。具体提供了一种有机电致发光器件,包括由一个或多个层组成的有机薄膜层,其中至少包括一个发光层,有机薄膜层被夹在阴极和阳极之间,以及用于有机薄膜层的至少一层的芳香胺衍生物,特别是用于传输空穴的层,该衍生物具有至少一种这样的结构,其中通过芳基基团将两个或更多个特定的杂环连接在一起的取代基,特别是通过芳基基团将两个或更多个特定的杂环连接在一起的取代基与胺基通过芳基基团键合。
