Abstract
New thiacalix[4]arenes appended with three amide functions have been prepared. Their conformations have been solved thanks to 1H NMR 2D correlation spectroscopy (COSY) and nuclear overhauser and exchange spectroscopy (NOESY). The complexation ability of these ligands towards various metal ions (Cd2 + , Pb2 + , Pd2 + , Ni2 + , Hg2 + , Hg+, Ag+, Zn2 + and Cu2 + ) has been investigated by the UV–vis absorption and the stoichiometry of the metal–ligand complexes was determined.
