Monolayers and LB Films - Controllable Layered Assembly

Formation of a bilayer structure is therefore driven by the self-assembhng behavior of amphiphilic molecules or molecular complexes. This research topic started from the dispersion of naturally-occurring phosphohpids in aqueous media, but the development of molecular design and systematic research has lead to the study of bilayer chemistry in various media. 

While bilayer cast films are oriented assemblies of amphiphiles, the number of layers in the films cannotbe controlled. However, precise control over the number of layers and the layering sequence is a crucial factor for many functional materials. Such functional materials have attracted much attention from re-

Monolayers and LB Films - Controllable Layered Assembly Some types of amphiphile form monolayer structures on the surface of water. These compressed monolayers can be transferred onto a sohd support in a layer-by-layer manner. This permits well-oriented multilayers to be created with defined numbers and sequences of layers.
