Dibenzoanthracene derivatives are each substituted by an amino compound group at 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): n n nwherein X 1 , X 2 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 or heterocyclic group, and between the adjacent groups, may be fused together to form rings; and Y 1 to Y 12 and R 1 each independently represents a hydrogen or halogen atom, an alkoxy group, or a substituted or unsubstituted alkyl, aryl or heterocyclic group, and, when Y 1 to U 12 and R 1 are other than a hydrogen or halogen atom, Y 1 to Y 12 and R 1 may be fused together between the adjacent groups to form rings. |
