Measurement of Solvent OH−π Interactions Using a Molecular Balance
A molecular
torsion balance was designed to study and measure OH−π
interactions between protic solvents and aromatic surfaces. These
specific solvent–solute interactions were measured via their
influence on the <i>folded</i>–<i>unfolded</i> equilibrium of an <i>N</i>-arylimide rotor. Protic solvents
displayed systematically weaker solvophobic interactions than aprotic
solvents with similar solvent cohesion parameters. This was attributed
to the formation of OH−π interactions between the protic
solvents and the exposed aromatic surfaces in the <i>unfolded</i> conformer that offset the stronger solvophobic effects for protic
solvents
