“…[ 160 ] It was shown that these spherical microparticles provide a mechanically and chemically rigid framework, pretecting dyes without hindering conformational transformation. The optical characteristics of photochromic dyes, fast rate constants for the thermal fading and position of absorption peaks, indicate that dyes are solubilized within the micellar phase of these microparticles.…”

The major advances in the field of the designed construction of hierarchically structured porous inorganic or hybrid materials wherein multiscale texturation is obtained via the combination of aerosol or spray processing with sol-gel chemistry, self-assembly and multiple templating are the topic of this review. The available materials span a very large set of structures and chemical compositions (silicates, aluminates, transition metal oxides, nanocomposites including metallic or chalcogenides nanoparticles, hybrid organic-inorganic, biohybrids). The resulting materials are manifested as powders or smart coatings via aerosol-directed writing combine the intrinsic physical and chemical properties of the inorganic or hybrid matrices with defined multiscale porous networks having a tunable pore size and connectivity, high surface area and accessibility. Indeed the combination of soft chemical routes and spray processing provides "a wind of change" in the field of "advanced materials". These strategies give birth to a promising family of innovative materials with many actual and future potential applications in various domains such as catalysis, sensing, photonic and microelectronic devices, nano-ionics and energy, functional coatings, biomaterials, multifunctional therapeutic carriers, and microfluidics, among others.

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

Nanostructured Materials Preparation via Condensation Ways

This method called sol-gel or dip-and spin-on-glass process, spin-spray-coating, sol -gel glasses, which was widely used in the second half of the twentieth century [1] 1 is one of the most universal condensation ways of production of nanoparticles stabilized by inorganic oxide or polymeric matrices. A special interest is attracted to materials obtained by combination of sol-gel chemistry and aerosol or spray processes, and combination of sol-gel synthesis with intercalation. This also includes combinations of sol-gel processes with different types of thermolysis, and approaches met in nature in biomineralization processes, etc., which are new aspects of integrative chemistry approach. Traditional sol-gel concept is based on hydrolysis and condensation of metal alkoxides and many metalloids including different ways of their modification [2,3]. Main reactions proceed at relatively low temperatures with usage of prepared in advance or synthesized in parallel polymers, and are convenient techniques for preparation of organic-inorganic nanocomposites compared with commercial silicate-intercalation technique. Sizes of formed nanoparticles in a composite can be reduced to 10 nm by choice of relative conditions. Polymer-inorganic materials have high mechanical strength and thermal stability in combination with optimal heat transport properties. They are widely used in practice due to unique physical and chemical properties: incorporation of nanometric inorganic component into polymeric matrix improves mechanical properties of material [4][5][6][7], permeability of polymers [8]. Light-sensitive materials are used in optic and electronic industry, printed-circuit boards, photoconductive cells, as key elements in solid coatings, packing materials, as cover materials they have good transparency [9][10][11]. For example, sol-gel method was used to produce various polymer/TiO 2 composites with high refractive index [12]. Such type of composites are used for chromatographic carriers, membrane materials, these are the main class of plastics for different applications, including airspace. Controlled properties of the surface of these colloid 1 We refer here to the recent review devoted to celebration of 40th anniversary of innovation researches in polymer-inorganic ceramics produced by sol-gel technique [1].
