    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.

    摘要: Provided are an organic electroluminescence device that not only provides high efficiency but also has a long lifetime, and an aromatic amine derivative that realizes the device. The organic electroluminescence device includes an aromatic amine derivative, including at least one substituent A having dibenzofuran and at least one substituent B selected from groups each having dibenzofuran or carbazole, in a molecule thereof, in which the substituent A and the substituent B include groups different from each other, and the substituent A and the substituent B are bonded to the same nitrogen atom, or different nitrogen atoms, in the molecule. The molecules of the aromatic amine derivative hardly crystallize, which improves a yield in the production of the organic electroluminescence device. In the 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, the aromatic amine derivative is contained in at least one layer, particularly a hole transport layer, in the organic thin film layer.
