  "title": "Aromatic amine derivative and organic electroluminescence element",
  "abstract": "A novel aromatic amine derivative having an asymmetric structure; and an organic electroluminescence device comprising a cathode, an anode and an organic thin film layer which is disposed between the cathode and the anode and comprises at least one layer comprising a light emitting layer, wherein at least one layer in the organic thin film layer comprises the above aromatic amine derivative singly or as a component of a mixture. Crystallization of the molecules is suppressed, and the yield in the production of the organic electroluminescence device can be increased.",
  "claims": [
    "1. An aromatic amine derivative represented by following general formula (1): A-L-B (1) wherein A represents a diarylamino group represented by: B represents a diarylamino group represented by: Ar 1 to Ar 4 each independently representing a substituted or unsubstituted aryl group having 5 to 50 nuclear atoms, and the two diarylamino groups represented by A and B being not same with each other; and L represents a linking group comprising a substituted or unsubstituted arylene group having 5 to 50 nuclear atoms or a linking group comprising a plurality of substituted or unsubstituted arylene groups having 5 to 50 nuclear atoms bonded with each other through a single bond, oxygen atom, sulfur atom, nitrogen atom or a saturated or unsaturated divalent aliphatic hydrocarbon group having 1 to 20 nuclear carbon atoms.",
    "2. An organic electroluminescence device comprising a cathode, an anode and an organic thin film layer which is disposed between the cathode and the anode and comprises at least one layer comprising a light emitting layer, wherein at least one layer in the organic thin film layer comprises an aromatic amine derivative described in claim 1 singly or as a component of a mixture.",
    "3. An organic electroluminescence device according to claim 2, wherein the organic thin film layer comprises a hole transporting zone, and the hole transporting zone comprises an aromatic amine derivative described in claim 1 singly or as a component of a mixture.",
    "4. An organic electroluminescence device according to claim 2, wherein the organic thin film layer comprises a hole transporting layer, and the hole transporting layer comprises the aromatic amine derivative singly or as a component of a mixture.",
    "5. An organic electroluminescence device according to claim 4, wherein the hole transporting layer comprises the aromatic amine derivative as a main component.",
    "6. An organic electroluminescence device according to claim 2, wherein the organic thin film layer comprises 30 to 100% by mole of the aromatic amine derivative."
