AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

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 derivative hardly crystallize, organic electroluminescence devices improving their production yield and having prolonged lifetime are provided.

AROMATIC AMINE DERIVATIVE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

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.
