Two benzimidazole-containing Schiff bases 2 (2′-hydroxybenzylidene)-aminobenzimi-dazole (HBA) and 2-(2′-hydroxynaphthylidene)-aminobenzimidazole (HNA),which have no substituted alkyl chains, have been found to form stable monolayers at the air/water interface in the presence of Ag(I) ion in the subphase. It has been found from UV-vis spectra and XPS measurements that the complex formation between the Schiff bases with Ag(I) ion induced the monolayer formation.
