Abstract:
An organic electroluminescence device having a layer of an organic light emitting medium which comprises (A) a specific arylamine compound and (B) at least one compound selected from specific anthracene derivatives, spirofluorene derivatives, compounds having condensed rings and metal complex compounds and is disposed between a pair of electrodes and an organic light emitting medium comprising the above components (A) and (B) are provided. The organic electroluminescence device exhibits a high purity of color, has excellent heat resistance and a long life and efficiently emits bluish to yellowish light. The organic light emitting medium can be advantageously used for the organic electroluminescence device.

Claim (Index 1):
An electroluminescence device comprising a pair of electrodes and a layer of an organic light emitting medium disposed between the pair of electrodes, wherein the layer of an organic light emitting medium comprises:\n (A) at least one compound selected from substituted and unsubstituted arylamines having 10 to 100 carbon atoms, and (B) at least one compound selected from:\n anthracene derivatives represented by following general formula (I):\n A 1 -L-A 2 \u2003\u2003(I) \n \n wherein A 1  and A 2  each independently represent a substituted or unsubstituted monophenylanthryl group or a substituted or unsubstituted diphenylanthryl group and may represent a same group or different groups, and L represents a single bond or a divalent bonding group,\n anthracene derivatives represented by following general formula (II):\n A 3 -An-A 4 \u2003\u2003(II) \n \n wherein An represents a substituted or unsubstituted divalent anthracene residue group, A 3  and A 4  each independently represent a substituted or unsubstituted aryl group having 6 to 40 carbon atoms, at least one of A 3  and A 4  represents a substituted or unsubstituted monovalent condensed aromatic ring group or a substituted or unsubstituted aryl group having 10 or more carbon atoms, and A 3  and A 4  may represent a same group or different groups,\n spirofluorene derivatives represented by following general formula (III): \n wherein Ar 1  represents a substituted or unsubstituted spirofluorene residue group, A 5  to A 8  each independently represent a substituted or unsubstituted aryl group having 6 to 40 carbon atoms,\n compounds having condensed rings represented by following general formula (IV): \n wherein Ar 2  represents a substituted or unsubstituted aromatic ring group having 6 to 40 carbon atoms, A 9  to A 11  each independently represent a substituted or unsubstituted arylene group having 6 to 40 carbon atoms, A 12  to A 14  each independently represent hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, an alkoxyl group having 1 to 6 carbon atoms, an aryloxyl group having 5 to 18 carbon atoms, an aralkyloxyl group having 7 to 18 carbon atoms, an arylamino group having 5 to 16 carbon atoms, nitro group, cyano group, an ester group having 1 to 6 carbon atoms or a halogen atom, and at least one of A 9  to A 14  represents a group having condensed aromatic rings, and metal complex compounds.
