Keeping in tune the global developments we are creating an institutional repository using DSpace Software (Digital Library Software). We are archiving institutional knowledge like, faculty papers, theses, and dissertations in PDF format at DSpace. Students can access this digital information anywhere in the campus.

| Abstract: | 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. |
