Self-Assembled Monolayers and Multilayers

SA monolayers spontaneously form, by definition, upon the immersion of a substrate into an organic solution of a suitable surfactant. The method is attractive since it avoids the complex mechanical manipulation required for making LB films and it is amenable, at least in principle, to scale-up. Conditions for the reproducible formation of highly ordered, well-packed, and stable monolayers and multilayers have only been established during the last decade.

The synthesis, characterization and properties of nanomaterials have become very active areas of research in the last few years. In particular, nanostructured materials assembled by means of supramolecular organization offer many exciting possibilities. These include self-assembled monolayers and multilayers with different functionalities, intercalation in preassembled layered hosts and inorganic three-dimensional networks. The reader is referred to the special issue of Chemistry of Materials91 for an overview of present day interests. There are many recent reviews on the varied aspects of nanomaterials. The work of Alivisatos92 on the structural transitions, elec-... 

D and 3D assemblies have been made by using a large variety of techniques, such as template-directed assembly, solvent evaporation, Langmuir-Blodgett (LB) transfer, producing self-assembled monolayers and multilayers, and layer-by-layer assembly.

As already introduced in Section 2.4, angular dependent NEXAFS spectroscopy is a powerful tool in the study of self assembled systems, and was successfully applied to the investigation of self assembled monolayers and multilayers of molecular-based NLO materials. Among others, Bubeck and co-workers [70] investigated the interaction of Cu " with C, N and O moieties in nanocomposites containing copper ions complexed in poly(amidoamine-organosilicon), PAMAMOS (dendrimer molecular structure is shown in Fig. 4.19).
