| Abstract: | Novel ditopic receptors of tetraamide derivatives possessing four 2-pyridyl groups derived from thiacalix4]arene in cone- and 1,3-alternate conformation were prepared. The structure of one of the tetraamide derivatives was confirmed by a single crystal X-ray analysis. The tetrathiacalix4]arene tetraamides show strong intramolecular hydrogen bonding. The binding behaviour towards Ag+ and halides has been investigated by 1H NMR titration experiments. |
