Abstract:
A fused aromatic ring derivative shown by the following formula (1): wherein Ra and Rb are independently a hydrogen atom or a substituent, m and n are independently an integer of 1 to 13, and when m and n are two or more, Ras and Rbs may be independently the same or different, and L1 is a single bond or a substituted or unsubstituted divalent linking group, provided that the fused aromatic ring derivative shown by the formula (1) does not have an anthracene ring.
