In the title compound, C32H28N2·CH2Cl2, the complete Schiff base and solvent molecules are both generated by crystallographic twofold axes, with the two C atoms of the former and the C atom of the latter lying on the rotation axis. The central benzene ring is substituted with two chiral groups including imine functionalities, with the common E configuration. The dihedral angle between the central benzene ring and the terminal naphthalene ring is 45.42 (9)° and that between the two naphthalene rings is 89.16 (8)°. The conformation of the Schiff base allows solvent mol­ecules to fill the voids in the crystal, affording a stable 1:1 solvate, but the solvent inter­acts poorly with the Schiff base, as reflected by its rather high displacement parameters.
