Metal complexes of salicylideneamines exhibit very interestingproperties and have been well characterizedsince the late 1920s. Amphiphilic salicylideneamines have beensynthesized in order to introduce suchcomplexes in Langmuir-Blodgett multilayers. They do nothydrolyze under the applied experimentalconditions and form stable monolayers. On subphases containingtransition metal ions, these compoundsform square-planar metal complexes by an interfacial reaction.Monolayers of these complexes have beentransferred onto solid substrates to prepare Langmuir-Blodgettmultilayers. Spectroscopic measurementswith polarized light indicate an orientation of the complex planenearly parallel to the substrate surface.In addition, monolayer experiments with presynthesized amphiphilicmetal complexes have been carriedout. Available hydroxyl groups in such complexes may be exploitedto construct aggregates due to theability of the molecules to form intermolecular bonds. Monolayersof these aggregates have also been usedfor the preparation of multilayers.
