Abstract

The lower rim functionalized cone-hexahomotrioxacalix[3]arene tris(2-pyridylamide) derivatives cone-3 and cone-7 having the hydrogen bonding groups and 2-pyridyl groups were synthesized from triol 1 by a stepwise reaction. Extraction data for alkali metal ions, transition metal ions, and alkyl ammonium ions from water into dichloromethane are discussed. Due to the strong intramolecular hydrogen bonding between the neighboring NH and CO groups, their affinities to metal cations were weakened. The complexation modes of cone-3 and cone-7 with n-BuNH3Cl and AgSO3CF3 were also demonstrated by 1H NMR titration in CDCl3. Tris(2-pyridylamide) derivatives cone-3 and cone-7 can complex with n-butyl ammonium ion and silver cation at the same time to form the heteroditopic complexation.
