The title compound, C(31)H(25)NO(6), has a structure related to other 3,4-diaryl-substituted maleic anhydride derivatives which have been shown to be useful as photochromic materials. The dihedral angles between the maleimide ring system and the benzene rings bonded to it are 44.48 (3) and 17.89 (3)°, while the angles between each of the latter rings and the corresponding ether bridging connected meth-oxy-benzene rings are 78.61 (8) and 72.67 (7)°. In the crystal, the molecules are linked by C-H⋯O inter-actions.
