In the title compound, C26H16N2O, the pyrene ring system (r.m.s. deviation = 0.021 Å) is inclined to the planar quinoline ring system (r.m.s. deviation = 0.017 Å) by 30.62 (5)°, and the conformation about the bridging N=C bond is E. There is an intramolecular O—H...N hydrogen bond with an S(5) ring motif present. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers with an R22(14) ring motif, flanked by two R21(7) ring motifs. The dimers stack along the b axis with slipped parallel π–π interactions involving neighbouring molecules; the shortest π–π interaction involves aromatic rings of the quinoline ring system [inter-centroid distance = 3.6267 (11) Å].
