description

The title compound, C23H20O2, is a precursor of a pyrene-based supramolecular element for non-covalent attachment to a carbon nanotube. The asymmetric unit contains three independent molecules. The carboxylic acid group in each of these molecules serves as an intermolecular hydrogen-bond donor and acceptor, generating the commonly observed double O—H...O hydrogen-bond motif in an eight-membered ring. Weaker C—H...O, π–π [centroid–centroid distance = 3.968 (4) Å] and C—H...π interactions are also found in the crystal structure.
