The title compound, C 44 H 30 N 4 O 2 , was prepared from 6,6′-dibromo-2,2′-dieth­oxy-1,1′-binaphthalene through a coupling reaction with 4-(4,4,5,5-tetra­methyl-1,3,2-dioxaborolan-2-yl)benzaldehyde followed by a Knoevenagel reaction with malononitrile. The dihedral angle between the symmetry-related naphthalene ring systems is 68.82 (8)° while the dihedral angle between the the naphthalene ring system and the adjacent benzene ring is 16.92 (7)°. Four symmetry-independent mol­ecules which are linked by inter­molecular C—H⋯π inter­action generate the packing motif in the crystal structure. One of the CN groups is disordered over two sets of sites in a 0.60 (2):0.40 (2) ratio.
