    摘要： An organic electroluminescence device includes a first organic thin-film layer and a second organic thin-film layer between an anode and a cathode opposing the anode in this order from the anode side. The first organic thin-film layer includes a specific aromatic heterocyclic derivative A, and the second organic thin-film layer includes a specific aromatic heterocyclic derivative B. The aromatic heterocyclic derivative A and the aromatic heterocyclic derivative B are different from each other. The organic electroluminescence device is capable of driving at a low voltage and has a long lifetime.

    摘要： 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.

    摘要： A novel aromatic amine derivative which is a diamine compound having a p-terphenyl-4,4″-diyl structure. An organic electroluminescence device which is composed of one or more organic thin film layers including at least one light emitting layer sandwiched between a cathode and an anode. Since at least one of the organic thin film layers contains the aromatic amine derivative singly or combination of two or more, the tendency of molecular crystallization is reduced and the yield in the fabrication of electroluminescence devices is enhanced. The aromatic amine derivative enables the production of electroluminescence devices having a prolonged lifetime and a high efficiency even after storing at high temperatures.
