Calix(6)arene hydroxamic acids (III) are synthesised for the first time by reacting calix(6)arene acid chloride(II) with substituted hydroxylamines at low temperature in the presence of sodium bicarbonate. The p-carboxycalix(6)arene(I) is obtained by an acid catalysed condensation reaction of p-hydroxybenzoic acid and formaldehyde. These calixarenes are characterised by melting point, UV, IR, 1H NMR and mass spectra. The thermodynamic ionization constants of calixarene hydroxamic acids have been determined by a pH titration technique in dioxane-water media.
