Pi-Pi Interaction in the Complexes of the Pyridino-18-Crown-6 Host Molecules and Aromatic Ammonium Salts as Determined by 1H NMR Spectroscopy.
Abstract
Significant pi-pi interaction is found in the complexes of (S,S)-dimethylpyridino-18-crown-6 with (R)- and (S)-ALPHA-(1-Naphthyl)ethylammonium perchlorate. This finding is supported by the 1H NOESY NMR spectral technique, greater chemical shift changes of aromatic protons in both host and guest molecules upon complexation, and by molecular mechanics calculations.
