Patent ID: 8785003

Claim:
An organic EL device material comprising: a unit comprising a 3,5-biscarbazolylphenyl group a unit comprising a 4-carbazolylphenyl group; and a compound comprising a unit comprising a nitrogen-containing aromatic heterocyclic ring bonding the unit comprising the 3,5-biscarbazolylphenyl group and the unit comprising the 4-carbazolylphenyl group, wherein the organic EL material is represented by a formula (4) where: A 1 , A 2 and A 3 each represent a substituted or unsubstituted aromatic hydrocarbon group having 6 to 60 ring carbon atoms; Cz 1 to Cz 3 each independently represent a substituted or unsubstituted carbazolyl group and is allowed to be mutually the same or different; Y 1 and Y 2 each independently represent a hydrogen atom, a fluorine atom, a cyano group, a substituted or unsubstituted and linear, branched or cyclic alkyl group having 1 to 20carbon atoms, a substituted or unsubstituted and linear, branched or cyclic alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted and linear, branched or cyclic haloalkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted and linear, branched or cyclic haloalkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted and linear, branched or cyclic alkylsilyl group having 1 to 10 carbon atoms, a substituted or unsubstituted arylsilyl group having 6 to 30 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted aromatic heterocyclic group having 2 to 10 ring carbon atoms; a represents an integer of 0 to 3 and b represents an integer of 0 to 4; p and q each independently represent an integer of 0 to 3; when p is 2 or more, A 1 is allowed to be the same or different; and when q is 2 or more, A 2 is allowed to be the same or different
