In the title compound, C32H25NO2S2, the mean plane through the five-membered pyrrolidine ring, which exhibits an envelope conformation, makes dihedral angles of 82.3 (1) and 83.9 (9)° with the benzene ring and the acenaphthylene ring system, respectively. The dihedral angle between the thiophene rings is 19.0(3)°. The crystal structure shows C—H⋯π and π–π interactions [centroid–centroid distance = 3.869 (2) Å]
