In the mol-ecule of the title compound, C25H24FN, the dihedral angle between the best planes of the quinoline fragment (rings A and B) and the benzene ring (C) is 9.51 (4)°. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of weak C-H⋯F inter-actions. The mol-ecules are stacked into chains along the a axis by weak off-set π-π inter-actions between the A and C rings of translation-related mol-ecules with a centroid-centroid distance of 3.6440 (2) Å.
