In order to investigate the supramolecular assembly and interfacial coordination of special amphiphile, two Schiff Base compounds with alkyl chains and different azobenzene substituted groups were designed and synthesized, and their supramolecular assembly and interfacial properties were investigated by spectral and morphological measurements. It was found that the Schiff base compounds can be spread on water surface to form stable monolayer. When on the Cu(II) ions subphase, an in situ coordination can occur for all ligands. In addition, for the coordination process of C16SB-Me-Azo with Cu(II), there are obvious spectral changes for the alkyl chains. For all process, the headgroups in all amphiphiles have predominant effect in regulating the aggregation mode and spectral changes in organized molecular films.
