All the complexes show high degrees of solvation, involving water and ethanol or methanol or acetone. The observed host/guest stoichiometry is determined in part by the nature of the solvent. A wide range of noncovalent interactions are observed in the various complexes, with the dominant interaction being hydrogen bonding and aromatic−aromatic stacking.
