Abstract
Calix[4]arenes bearing aromatic amide (aramid) moieties at the upper rim display interesting recognition properties toward anions and in particular versus planar trigonal nitrate and Y-shaped benzoate. Molecular modeling and DFT calculations indicate that the high affinity displayed by aramidocalix[4]arenes 3 and 4 for nitrate anion is likely due to the planar arrangement of the NH groups, which form an unusual six-hydrogen-bond scheme with nitrate anionFile in questo prodotto:
