 Abstract: New amphiphilic schiff bases 2.4 dihydroxy hexadecyl benzilideneamine (HDBA) and 2,4 dihydroxy benzilidene4'(hexadecylamino) benzylamine (HDBBA) have been synthesized and stable monolayers of these at air/water interface have been studied. Complexes of these ligands with metal ions Mn2+, Cu2+ and Zn2+ at the interface have been possible due mainly to the presence of the hydroxyl group adjacent to C=N in the head groups, in both the ligands. These metal complexes have been studied using surface pressure/molecular area (pi-A), surface potential! molecular area (DeltaV-A) isotherms and surface enhanced UV-Vis reflection spectroscopy. The rate of formation of the metal complexes with the ligands HDBA and HDBBA at the liquid/water interface has been studied. The Faster rate of formation of Cu2+ complex in the case of HDBBA indicates the specificity of binding of Cu2+ ion to its monolayer. (C) 2002 Elsevier Science B.V. All rights reserved.
