“…The dispersion of metallophtalocyanine dyes with interesting RSA into SiO 2 sol-gel matrices was firstly reported. [157,337] The RSA of the dyes was also observed in the solid materials demonstrating the capacity of the strategy. The presence of dimers showed that the dyes were not totally homogeneously dispersed, and protonated species which showed that the process should be adapted to the dyes sensitivity (Control of pH .…”

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”.

Nowadays the sol–gel process is used by an increasing number of researchers for the preparation of various products, including bulk materials, films, membranes or fibers. The application of ultrasound (sonocatalysis) to the precursors gives rise to materials with new properties, known as sonogels. The absence of additional solvent and, mainly, the effects of ultrasonic cavitation create a unique environment for sol–gel reactions leading to particular features in the resulting gels: high density, fine texture, homogeneous structure etc. These properties determine the evolution of sonogels on further processing and the final material structure. In this sense, the full exploitation of sonocatalysis requires a thorough understanding of the processes involved and their sensitivity to reaction parameters. For this purpose, we have used diverse techniques to investigate the microstructural evolution during different steps in the sonogel process. The results of these studies are reported here. Finally, we present an overview of some applications for which the mechanical, textural and optical characteristics of sonogels are quite useful. Copyright © 1999 John Wiley & Sons, Ltd.

High power ultrasound applied to liquids produces cavities that attain very high temperatures and pressures ("hot spots"). When an alkoxide/water mixture is sonicated, the cavities act as nanoreactors, where the hydrolysis reaction starts. The products (alcohol, water, and silanol) help continue the dissolution of that immiscible mixture. The reactions depend on catalyst content, temperature bath, and alkyl group length. When the resultant sonosol gels, it produces a sonogel; it is denser, with finer and more homogeneous porosity than that of a classic counterpart. Thus, acoustic cavitation makes it possible to obtain nanostructured materials. Sono-aerogels have a high surface-to-volume ratio and are built by small particles (~1 nm radius) and a highly cross-linked network with low surface coverage of -OH radicals. The processing as well as their short-range order at an atomic scale and at a micrometric scale is presented in this chapter. Finally, these materials find application, among others as biomaterials for tissue engineering and for CO 2 sequestration. 20
