摘要 |
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. |
