In the triarylamine group of the title compound, C26H20N2O2, the N atom adopts an approximately trigonal–planar geometry, lying 0.046 (5) Å from the plane P defined by its three neighbouring C atoms; the benzene and two terminal phenyl rings are twisted by 37.4 (1), 31.4 (1) and 47.8 (1)°, respectively from plane P. In the trans-stilbene fragment, the two benzene rings form a dihedral angle of 31.3 (1)°. In the crystal, weak intermolecular C—H⋯O interactions link the molecules into ribbons in .
