Abstract:
A fused aromatic 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, and when p and q are two or more, Ras and Rbs may be independently the same or different, and adjacent substituents Ras may form a ring, 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 when L1 is a single bond and at least one of Ras is not a hydrogen atom, Ar1 is not a triphenylenyl group, and provided that substituents of L1 and Ar1, and Ra and Rb contain no amino group.
