Material for organic electroluminescent device and organic electroluminescent device using same

A material for an organic electroluminescence device which comprises a compound represented by general formula (1):

• wherein Cz represents a carbazolyl group, an arylcarbazoleyl group having 18 to 60 carbon atoms, an azacarbazolyl group, an arylazacarbazoleyl group having 18 to 60 carbon atoms, an acridinyl group, a phenoxazinyl group or dibenzoazevinyl group each may have a substituent;
• Ar1 and Ar2 each independently represents a substituted or unsubstituted aryl group having 6 to 60 carbon atoms or a substituted or unsubstituted heterocyclic group having 3 to 60 carbon atoms;
• Ar3 represents an aromatic hydrocarbon group having 6 to 60 carbon atoms or a substituted or unsubstituted heterocyclic group having 3 to 60 carbon atoms;
• Ar4 represents a substituted or unsubstituted benzene residue, a substituted or unsubstituted thiophene residue, a substituted or unsubstituted triazole residue, a substituted or unsubstituted fluorene residue or a substituted or unsubstituted spirobifluorene residue;
• a represents an integer of 0 or 1, b represents an integer of 0 to 4, and c represents an integer of 1 to 3;
• and when there are plural of Cz and when there are plural of Ar4, they may be the same with or different from each other;
• with a proviso that when a=0 and c=1, a case where both Ar3 and Ar4 represent benzene residues and Ar2 represents a phenyl carbazolyl group or a carbazolyl group is omitted;
• further, when a=1, b=0 and c=1, a case where Ar3 represents a benzene residue and both Ar1 and Ar2 represent phenyl carbazolyl groups is omitted;
• and
• furthermore, when b=0 and c=1, a case where Ar3 represents a benzene residue and all of Ar1, Ar2 and Cz represent a carbazolyl group or a phenyl carbazolyl group is omitted.
