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.
在标题化合物C₃₆H₂₈O₄中，中心2,7 - 二乙氧基萘环体系1位和8位的1 - 萘甲酰基几乎呈反平行排列，二面角为76.59 (4)°。中心2,7 - 二乙氧基萘环体系与末端萘环体系之间的二面角分别为86.48 (4)°和83.97 (4)°。在晶体中，沿着a轴观察到中心萘环体系与萘甲酰基之间存在C—H⋯π相互作用，分子形成柱状结构。这些柱通过C—H⋯O相互作用连接成平行于b轴的链。
