In the title compound, C39H26O, the cyclopenta[a]acenaphthylene skeleton displays the expected distortions, with formal sp2 bond angles as high as C—C—C = 142.50 (10)°. The OH group forms intermolecular hydrogen bonds via x-axis translation to the centroid (Cg) of the pendant phenyl ring of the biphenyl system, with H...Cg = 2.41 Å and O—H...Cg = 153°.
