In the title compound, C36H28O4, the two 2-naphthoyl groups at the 1- and 8-positions of the central 2,7-dieth-oxy-naphthalene ring system are aligned almost anti-parallel and make a dihedral angle of 48.35 (5)°. The dihedral angles between the central 2,7-dieth-oxy-naphthalene ring system and the terminal naphthalene ring systems are 77.64 (4) and 73.73 (4)°. In the crystal, mol-ecules are linked into chains along the a-axis direction by dual C-H⋯O inter-actions between naphthoyl groups.
