A material for an organic electroluminescence device represented by the formula (3):

• wherein:
• R1 independently represents a substituted or unsubstituted aromatic hydrocarbon group having a ring formed of 6 to 24 carbon atoms or a substituted or unsubstituted aromatic heterocyclic group having a ring formed of 3 to 24 atoms, provided that at least one R1 represents a dibenzofuranyl or a dibenzothiophenyl each being optionally substituted by a substituent selected from the group consisting of an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group having a ring formed of 3 to 40 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a cycloalkoxy group having a ring formed of 3 to 10 carbon atoms, an aromatic hydrocarbon group having a ring formed of 6 to 40 carbon atoms, and amino group substituted with an aromatic hydrocarbon group having a ring formed of 6 to 40 carbon atoms, an ester group having an aromatic hydrocarbon group having a ring formed of 6 to 40 carbon atoms, an ester group having 1 to 6 carbon atoms, a cyano group, a nitro group, and a halogen atom;
• L1 represents a single bond, a substituted or unsubstituted, monovalent or divalent aromatic hydrocarbon group having a ring formed of 6 to 24 carbon atoms, or a substituted or unsubstituted, monovalent or divalent aromatic heterocyclic group which has a ring formed of 3 to 24 atoms and which is linked with the benzene ring a through a carbon-carbon bond;
• L2 represents a single bond, a substituted or unsubstituted, monovalent or divalent aromatic hydrocarbon group having a ring formed of 6 to 24 carbon atoms, or a substituted or unsubstituted, monovalent or divalent aromatic heterocyclic group which has a ring formed of 3 to 24 atoms and which is linked with the benzene ring c through a carbon-carbon bond;
• A1 represents a hydrogen atom, a substituted or unsubstituted aromatic hydrocarbon group having a ring formed of 6 to 24 carbon atoms, or an aromatic heterocyclic group which has a ring formed of 3 to 24 atoms and which is linked with L1 through a carbon-carbon bond;
• A2 represents a hydrogen atom, a substituted or unsubstituted aromatic hydrocarbon group having a ring formed of 6 to 24 carbon atoms, or an aromatic heterocyclic group which has a ring formed of 3 to 24 atoms and which is linked with L2 through a carbon-carbon bond, provided that, when both L1 and L2 represent single bonds, a case where A1 and A2 simultaneously represent hydrogen atoms is excluded;
• Y1, Y2, and Y3 each represent a substituted or unsubstituted aromatic hydrocarbon group having a ring formed of 6 to 24 carbon atoms or a substituted or unsubstituted aromatic heterocyclic group which has a ring formed of 3 to 24 atoms and which is linked with the benzene ring a, b, or c through a carbon-carbon bond;
• a number of each of Y1 and Y3 is 0, 1, 2, or 3;
