Resumen
New N-p-chloro-, N-p-bromo-, and N-p-nitrophenylazobenzylchitosan derivatives, as well as the corresponding azophenyl and azophenyl-p-sulfonic acids, were synthesized by coupling N-benzylvchitosan with aryl diazonium salts. The synthesized molecules were analyzed by UV-Vis, FT-IR, 1H-NMR and 15N-NMR spectroscopy. The capacity of copper chelation by these materials was studied by AAS. Chitosan and the derivatives were subjected to hydrolysis and the products were analyzed by ESI(+)-MS and GC-MS, confirming the formation of N-benzyl chitosan. Furthermore, the MS results indicate that a nucleophilic aromatic substitution (SnAr) reaction occurs under hydrolysis conditions, yielding chloroaniline from N-p-bromo-, and N-p-nitrophenylazo-benzylchitosan as well as bromoaniline from N-p-chloro-, and N-p-nitrophenylazobenzyl-chitosan. 19 11 17604 17618 Fernández, R., Ramos, J.A., Espósito, L., Tercjak, A., Mondragon, I., Reversible Optical Storage Properties of Nanostructured Epoxy-Based Thermosets Modified with Azobenzene Units (2011) Macromolecules, 44, pp. 9738-9746 Manickasundaram, S., Kannan, P., Hassan, Q.M.A., Palanisamy, P.K., Azo dye based poly(alkyloxymethacrylate)s and their spacer effect on optical data storage (2008) J.
