The asymmetric unit of the title compound, C49H36O6·CHCl3, contains half an organic molecule, the complete molecule being generated by the operation of a crystallographic twofold rotation axis, and half a highly disordered chloroform molecule. The contribution to the diffraction pattern of the latter was removed using the program SQUEEZE in PLATON [Spek (2009). Acta Cryst. D65, 148–155]; the unit-cell characteristics take into account the presence of CHCl3. The dihedral angles between the planes of the naphthalene ring system and the methoxybenzene rings are 71.05 (7) (syn to the central C=O group) and 57.27 (6)° (anti to the central C=O group). In the crystal, molecules are linked by C—HO interactions, generating C(12) chains running parallel to the b axis.
