Hybrid materials based supramolecular organic

In this chapter, supramolecular chemistry related to developments in materials fabrication and functionalization at the mesoscale are discussed, with an emphasis on those systems based on organic-inorganic hybrid structures. The contents of this chapter are classified into (1) supramolecular chemistry within mesoscopic media, (2) supramolecular assembly at the mesoscale, and (3) supramolecular materials at the mesoscale. Despite this classification these topics have considerable similarities. 

At the crossover between supramolecular and synthetic chemistry the hybrid materials represent a major field of science exploration and applications. In contrast with pure silica, the presence of the organic groups in R-[SiO, 5] (n>l) systems questions the possibility to have organization based on the presence of hydrophobic and hydrophilic parts. 

During the last decades, several studies reported the preparation of synthetic discrete supramolecular assemblies (4-8), polymers (1-9), and hybrid materials (10-12) that possess bases of nucleic acids as side groups or chain-end, which are used as precursors to conceive self-organized hybrid materials at nanometric scale.
