Porous materials, supramolecular assemblies

In addition to mesostructured metal oxide molecular sieves prepared through supramolecular assembly pathways, clays, carbon molecular sieves, porous polymers, sol-gel and imprinted materials, as well as self-assembled organic and other zeolite-like materials, have captured the attention of materials researchers around the globe. Clays, zeolites and sol-gel materials are still very popular because of their extensive and expanding applications in catalysis and separation science. Novel carbons and polymers of ordered porous structures have been synthesized. There are almost unlimited opportunities in the synthesis of new organic materials of desired structural and surface properties via self-assembly or imprinting procedures.

Metal—carboxylato—nucleobase systems From supramolecular assemblies to 3D porous material 13CCR2716. 

We described the development of calixarenes and pillarenes on surfaces and the applications of these hybrid materials. The selected surfaces include NPs, metal surface. Si surface, electrode, porous materials, and carbon materials. These multivariant hybrid materials combine the supramolecular host-guest properties of calixarene/pillarene hosts with the unique surface properties of other entities, expand the applications in recognition, stabilization, self-assembly, dispersion, electrode, controlled drug release, sensing, separation and absorption. This design principle holds great promise for the design and application of new desired materials in future. 

In this chapter we describe the basic principles involved in the controlled production and modification of two-dimensional protein crystals. These are synthesized in nature as the outermost cell surface layer (S-layer) of prokaryotic organisms and have been successfully applied as basic building blocks in a biomolecular construction kit. Most importantly, the constituent subunits of the S-layer lattices have the capability to recrystallize into iso-porous closed monolayers in suspension, at liquid-surface interfaces, on lipid films, on liposomes, and on solid supports (e.g., silicon wafers, metals, and polymers). The self-assembled monomolecular lattices have been utilized for the immobilization of functional biomolecules in an ordered fashion and for their controlled confinement in defined areas of nanometer dimension. Thus, S-layers fulfill key requirements for the development of new supramolecular materials and enable the design of a broad spectrum of nanoscale devices, as required in molecular nanotechnology, nanobiotechnology, and biomimetics [1-3].
