Integrative chemistry of functional nanostrustructured and hierarchically
structured Inorganic and hybrid materials

Hybrid inorganic-organic materials can be broadly defined as synthetic
materials with organic and inorganic components which are intimately mixed.
They can be either homogeneous systems derived from monomers and miscible
organic and inorganic components, or heterogeneous and phase-separated
systems where at least one of the components’ domains has a dimension
ranging from a few Å to several nanometers. Hybrid phases can also be used
to nanostructure or texture new inorganic nanomaterials (porous or
non-porous). The versatile synthetic conditions provided by bottom-up
strategies such as reactive molecular precursors or clusters, tunable
processing temperatures and solvents and the adjustable rheology of the
colloidal state allow for the mixing of the organic and inorganic
components at the nanometer scale in virtually any ratio. These features,
and the advancement of organometallic chemistry and polymer and sol-gel
processing, make possible a high degree of control over both composition
and structure (including nanostructure) of these materials, which present
tunable structure-property relationships. This, in
turn, makes it possible to tailor and fine-tune properties (mechanical,
optical, electronic, thermal, chemical…) in very broad ranges, and to
design specific systems for applications. Hybrid materials can be processed
as gels, monoliths, thin films, fibers, particles or powders or can be
intermediates to design materials having complex shapes or hierarchical
structures. The seemingly unlimited variety, unique structure-property
control, and the compositional and shaping
flexibility give these materials a high potential in sensing, membranes,
catalysis, biocatalysis, photocatalysis, nanomedicine, the tailoring of
smart functional surfaces etc. This lecture will describe some recent
advances on this integrative materials chemistry that allows via a
chemistry-process coupling to tailor made nanostructured and hierarchically
structured functional inorganic and hybrid materials.
