Bottom up approaches to Inorganic and Hybrid Organic-Inorganic Nanostructured Materials

Inorganic and hybrid nano-composites materials can be obtained either through hydrolysis and condensation reactions of functional metal alkoxides or chlorides or through the assembly of well defined nanobuilding blocks (NBBs). The properties that can be expected for such hybrid materials of course depend on the chemical nature of their components but also on the extend and the nature of their interface. These hybrid NNBs can be clusters or functional nanoparticles which chemical control of their surface properties by using nucleophilic groups allows to tune their size and functionality. Moreover the use of texturing agents triggers the formation of tailor-made nano-phases. In particular, considerable effort is being currently directed to the synthesis of nanostructured porous transition metal oxides. The use of ordered lyotropic phases as templating agents leading to a mesoscopically ordered hybrid precursors allows to obtain long-range nanostructured hybrid or metal oxide phases shaped as thin films. These nanomaterials can be used as new plateforms to develop composite nanolayers with sensing, catalytic or magnetic properties.. Some examples concerning the design of inorganic and hybrid nanomaterials made via bottum-up approaches to create nanostructured ordered phases will be presented together with some of their properties.
