Page/Page column 31-32, (2012/02/15)
There are provided an aromatic monoamine derivative having a fluorene structure-containing organic group and an aromatic hydrocarbon group-containing organic group, and an organic electroluminescent element containing an organic thin film layer composed of a single layer or plural layers while including at least a light emitting layer, the organic thin film layer being between a cathode and an anode, wherein at least one layer of the organic thin film layer, particularly a hole transport layer, contains the aromatic amine derivative alone or as a component of a mixture. An organic electroluminescent element which maintains high luminous efficiency even if exposed to a high temperature environment, and has a low driving voltage and a long emission lifetime, and an aromatic amine derivative capable of realizing the organic electroluminescent element are provided.

Page/Page column 26; 37, (2012/01/11)
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.

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.

Page/Page column 69, (2008/06/13)
Disclosed is an organic electroluminescent device wherein an organic thin film which is composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains a novel aromatic amine derivative, which has an asymmetric structure wherein two different amine units are bonded through a linking group, by itself or as a component of a mixture, molecules are hardly crystallized, thereby improving the production yield of the organic electroluminescent device. This organic electroluminescent device has a long life.
