Planar supramolecular chemistry

Assembling problem of organized functional surfaces (active matrices) and ultra-thin multilayer films, controlled heterogeneous structure of which determines the unique binding and transport properties of species are discussed. Several tuning strategies of 2D films of amphiphilic and non-amphiphilic compounds (ligands, complexes and ionophores) for effective ionic/molecular transfer within the films as well as for selective interactions with various species are considered. The novel approach utilizing the concept of “supramolecular pump” was used to produce the unique nanosized and highly sensitive LB sensors with ultra-fast response. The combined procedure based on self-assembled monolayer and LB techniques was applied in the design of double-layer biomimetic structures of metal complexes of amphiphilic bis-cyclen. The controlled self-assembling of nucleotides on these active planar matrices at physiological conditions was demonstrated. The stepwise chemical lithography proceeding from condensed multilayer LB film to hybrid and then to inorganic planar assemble of functional elements with a confined lateral geometry are discussed.
