Department of Organic and Polymer Materials Chemistry, Tokyo University of Agriculture & Technology, Koganei, Tokyo 184-8588, Japan.
In the title compound, C36H28O4, the 1-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 76.59 (4)°. The dihedral angles between the central 2,7-dieth-oxy-naphthalene ring system and the terminal naphthalene ring systems are 86.48 (4) and 83.97 (4)°. In the crystal, C-H⋯π inter-actions between the central naphthalene ring systems and the naphthoyl groups are observed along the a axis, with the mol-ecules forming a columnar structure. The columns are linked into chains parallel to the b axis by C-H⋯O inter-actions.
