In the title molecule, C23H17N3, the phenyl substituents at positions 1 and 4 are twisted relative to the central core by 27.09 (5) and 66.62 (4)°, respectively. In the crystal, molecules are assembled into centrosymmetric dimers via π–π stacking interactions between the 1H-pyrazolo[3,4-b]quinoline units, with an interplanar distance of 3.601 (2) Å and by weak intermolecular C—H⋯N interactions.
