Anthracene derivatives, luminescent materials and organic electroluminescent devices

An anthracene derivative, comprising a phenanthryl group, the anthracene derivative being represented by formula (1-1):

• wherein:
• L1 represents a single bond;
• Ar1 represents a group represented by formula (2):
• a substituted or unsubstituted fused aromatic ring group having 10 to 50 ring-forming carbon atoms, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted indenyl group, or a substituted or unsubstituted heterocyclic group having 5 to 50 ring-forming atoms, provided that
• when Ar1 represents a group other than a group represented by formula (2), and a 1-position of the phenanthryl group is bonded to an anthracene skeleton, Ar1 is not an unsubstituted 1-phenanthryl group,
• when Ar1 represents a group other than a group represented by formula (2), and a 2-position of the phenanthryl group is bonded to the anthracene skeleton, Ar1 is not a substituted or unsubstituted 2-phenanthryl group, and
• when Ar1 represents a group other than a group represented by formula (2), and a 3-position of the phenanthryl group is bonded to the anthracene skeleton, Ar1 is not an unsubstituted 3-phenanthryl group;
• substituents Rx, Ra, and Rb each independently represent a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 50 carbon atoms, a substituted or unsubstituted alkynyl group having 2 to 50 carbon atoms, a substituted or unsubstituted aralkyl group having 7 to 20 carbon atoms, a substituted or unsubstituted cycloakyl group having 3 to 20 carbon atoms, a substituted or unsubstituted alkoxyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 20 ring-forming carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 ring-forming carbon atoms, a substituted or unsubstituted heteroaryl group having 5 to 50 ring-forming atoms, a substituted or unsubstituted alkylsilyl group having 1 to 30 carbon atoms, a substituted or unsubstituted arylsilyl group having 6 to 50 ring-forming carbon atoms, a substituted or unsubstituted alkylgermanium group having 1 to 50 carbon atoms, or a substituted or unsubstituted arylgermanium group having 6 to 50 ring-forming carbon atoms;
• “p” represents an integer of 1 to 8;
• “q” represents an integer of 0 to 9;
• and “y” represents an integer of 0 to 4;
• when “p” represents 2 to 8, “q” represents 2 to 9, or “v” represents 2 to 4, a plurality of Rx's, a plurality of Ra's, or a plurality of Rh's are identical to or different from each other, provided that a case where all Rx, Ra, and Rb each represent an anthracenyl group is excluded;
• and
• Arz represents a substituent selected from the group consisting of a substituted or unsubstituted phenyl group, a substituted or unsubstituted indenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted benzofluorenyl group, a substituted or unsubstituted dibenzofluorenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted benzanthracenyl group, a substituted or unsubstituted naphthacenyl group, a substituted or unsubstituted fluoranthenyl group, a substituted or unsubstituted benzofluoranthenyl group, a substituted or unsubstituted triphenylenyl group, a substituted or unsubstituted chrysenyl group, a substituted or unsubstituted pyrenyl group, a substituted or unsubstituted benzophenanthryl group, a substituted or unsubstituted benzochrysenyl group, and a substituted or unsubstituted heterocycle comprising group having 3 to 50 nucleus forming atoms,
• when Arz has a plurality of substituents, a plurality of adjacent substituents are optionally bonded to each other to form a saturated or unsaturated divalent group that completes a ring, when a phenanthrene skeleton is bonded at its 1- or 2-position to the anthracene skeleton, Arz represents a group except an unsubstituted phenyl group, and when the phenanthrene skeleton is bonded at its 3-position to the anthracene skeleton, Rx and Arz each represent a group except an unsubstituted carbazolyl group.
