Abstract

Provided are a novel aromatic amine derivative having a specific structure and an organic electroluminescence device in which an organic thin layer comprising a single layer or plural layers including a light emitting layer is interposed between a cathode and an anode, wherein at least one layer of the above organic thin layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Thus, the organic electroluminescence device is less liable to be crystallized in molecules, improved in a yield in producing the organic electroluminescence device and extended in a lifetime.

Claims (25)

1. An organic electroluminescence device in which an organic thin layer comprising plural layers including at least a light emitting layer and a hole transporting layer is interposed between a cathode and an anode, wherein at least the hole transporting layer contains an aromatic amine derivative represented by the following Formula (5) in the form of a single component or a mixed component:

wherein at least one of Ar 7 to Ar 9 is represented by the following Formula (3):

wherein R 4 to R 6 each are independently a hydrogen atom, or a non-substituted aryl group having 5 to 50 ring carbon atoms;

X is an oxygen atom;

f and h each are an integer of 0 to 4; g is an integer of 0 to 3; and i is an integer of 1 to 3;

in Formula (5), among Ar 7 to Ar 9 , the groups which are not represented by Formula (3) each are independently a substituted or non-substituted aryl group having 5 to 50 ring carbon atoms.

2. The organic electroluminescence device as described in claim 1 , wherein styrylamine and/or arylamine is contained in the light emitting layer described above.

10. The organic electroluminescence device as described in claim 1 , wherein among Ar 7 to Ar 9 , the groups which are not represented by Formula (3) each are independently an non-substituted aryl group having 5 to 50 ring carbon atoms.

11. The organic electroluminescence device as described in claim 1 , wherein among Ar 7 to Ar 9 , the groups which are not represented by Formula (3) each are independently selected from the group consisting of a non-substituted phenyl group, a non-substituted biphenylyl group, a non-substituted terphenylyl group, and a non-substituted 9,9-dimethyl fluorenyl group.

12. The organic electroluminescence device as described in claim 1 , wherein Ar 7 is represented by Formula (3), Ar 8 is selected from the group consisting of non-substituted phenyl group, a non-substituted biphenylyl group, a non-substituted terphenylyl group, and a non-substituted 9,9-dimethyl fluorenyl group, and
