Abstract
A new water soluble receptor 5,11,17,23-tetrasulphonato-25,27-di droxy carbonylmethoxy)-26,28-dihydroxycalix[4]arene was synthesized and char acterized and its proton and copper(II) complexes were studied and com pared with the analogous species of the fully carboxylated ligand 5,11 ,17,23-tetrasulphonato ,28-tetrakis(hydroxycarbonylmethoxy)caliz[4]are ne. Delta H and Delta S degrees values are crucial for understanding t he peculiar acid-base properties of the ligand. EPR spectra together w ith the UV-VIS spectral data reveal the coordination stereochemistry o f the copper(II) species.
