Abstract

The inclusion of small neutral organic guests (acetonitrile, toluene, pyrazine, butylamine, nitromethane) by cyclic calix[4]arene diamide receptors was studied by 1H NMR spectroscopy. The binding constants determined by 1H NMR titration, and the results obtained by T1 relaxation measurements and DOSY confirm the importance of the acidity of the C-H bond of the guests and highlight the role of steric interactions including conformational properties of the receptors in the recognition process.
