Abstract:
Dibenzoanthracene derivatives are each substituted by an amino compound group at least one of 9-position and 14-position of a dibenzo[a,c]anthracene skeleton and represented by the following formula (1) or (2): wherein X1, X2 and X each independently represents a substituted or unsubstituted arylene or divalent heterocyclic group; A, B, C and D each independently represents a substituted or unsubstituted alkyl, aryl heterocyclic group, and between the adjacent groups, may be fused together to form rings; and Y1 to Y12 and R1 each independently represents a hydrogen atom, a halogen atom, an alkoxy group, or a substituted or unsubstituted alkyl, aryl or heterocyclic group, and, when Y1 to Y12 and R1 are other than a hydrogen atom or a halogen atom, Y1 to Y12 and R1 may be fused together between the adjacent groups to form rings.
