Abstract
A fused aromatic ring derivative shown by the following formula (1): wherein Ra and Rb are independently a hydrogen atom or a substituent, p is an integer of 1 to 8 and q is an integer of 1 to 11, when p is 2 or more, plural Ras may be independently the same or different and adjacent Ras may form a ring, when q is 2 or more, plural Rbs may be independently the same or different, L1 is a single bond, or a substituted or unsubstituted divalent linking group, and Ar1 is a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms or a substituted or unsubstituted heteroaryl group having 5 to 50 ring atoms, provided that the substituent of L1, the substituent of Ar1, Ra and Rb contain no substituted or unsubstituted amino group.

A fused aromatic ring derivative shown by the following formula (1):
- wherein Ra and Rb are independently a hydrogen atom or a substituent,
- p is an integer 1 to 8 and q is an integer of 1 to 11,
- when p is 2 or more, plural Ras may be the same or different and adjacent Ras may form a ring,
- when q is 2 or more, plural Rbs may be the same or different,
- L1 is a single bond, or a substituted or unsubstituted divalent linking group, and
- Ar1 is a substituted or unsubstituted aryl group and the aryl group is selected from the group consisting of a phenyl group, a naphthyl group, an anthryl group, a phenanthryl group, a naphthacenyl group, a pyrenyl group, a biphenyl group, a terphenyl group, and a benzophenathryl group, provided that the substituent of L1, the substituent of Ar1, Ra and Rb contain no substituted or unsubstituted amino group.
