AROMATIC AMINE DERIVATIVE AND ELECTROLUMINESCENCE DEVICE USING THE SAME

摘要

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 leas 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.

1. An aromatic amine derivative represented by the following Formula (1): wherein R1 is a hydrogen atom, a substituted or non-substituted aryl group having 5 to 50 ring carbon atoms, a substituted or non-substituted alkyl group having 1 to 50 carbon atoms, a substituted or non-substituted alkoxy group having 1 to 50 carbon atoms, a substituted or non-substituted aralkyl group having 6 to 50 carbon atoms, a substituted or non-substituted aryloxy group having 5 to 50 ring carbon atoms, a substituted or non-substituted arylthio group having 5 to 50 ring carbon atoms, a substituted or non-substituted alkoxycarbonyl group having 2 to 50 carbon atoms, an amino group substituted with a substituted or non-substituted aryl group having 5 to 50 ring carbon atoms, a halogen atom, a cyano group, a nitro group, a hydroxyl group or a carboxyl group; a is an integer of 0 to 4, and b is an integer of 1 to 3; plural R1 may be combined with each other to form a cyclic structure of a saturated or unsaturated five-membered ring or six-membered ring which may be substituted; at least one of Ar1 to Ar4 is represented by the following Formula (2): (wherein R2 and R3 each are selected independently from the same groups as those of R1 in Formula (1) described above; X is oxygen, sulfur, selenium or tellurium; c is an integer of 0 to 6; d is an integer of 0 to 3; and e is an integer of 1 to 3; plural R2 or R3 may be combined with each other to form a cyclic structure of a saturated or unsaturated five-membered ring or six-membered ring which may be substituted; when e is 2 or more and d is not 0, plural R3 may be combined with each other to form a cyclic structure of a saturated or unsaturated five-membered ring or six-membered ring which may be substituted); in Formula (1), among Ar1 to Ar4, the groups which are not represented by Formula (2) each are independently a substituted or non-substituted aryl group having 6 to 50 ring carbon atoms or a substituted or non-substituted aromatic heterocyclic group having 5 to 50 ring carbon atoms.
