Crystalline metal-organic frameworks (MOFs) are formed by reticular synthesis, which creates strong bonds between inorganic and organic units. Careful selection of MOF constituents can yield crystals of ultrahigh porosity and high thermal and chemical stability. These characteristics allow the interior of MOFs to be chemically altered for use in gas separation, gas storage, and catalysis, among other applications. The precision commonly exercised in their chemical modification and the ability to expand their metrics without changing the underlying topology have not been achieved with other solids. MOFs whose chemical composition and shape of building units can be multiply varied within a particular structure already exist and may lead to materials that offer a synergistic combination of properties.

Lanthanide-based luminescent hybrid materials.

Mesoporous organic-inorganic hybrid materials, a new class of materials characterized by large specific surface areas and pore sizes between 2 and 15 nm, have been obtained through the coupling of inorganic and organic components by template synthesis. The incorporation of functionalities can be achieved in three ways: by subsequent attachment of organic components onto a pure silica matrix (grafting), by simultaneous reaction of condensable inorganic silica species and silylated organic compounds (co-condensation, one-pot synthesis), and by the use of bissilylated organic precursors that lead to periodic mesoporous organosilicas (PMOs). This Review gives an overview of the preparation, properties, and potential applications of these materials in the areas of catalysis, sorption, chromatography, and the construction of systems for controlled release of active compounds, as well as molecular switches, with the main focus being on PMOs.

Mesoporöse organisch-anorganische Hybridmaterialien auf Silicabasis

Mesoporous organic–inorganic hybrid materials are an interesting class of materials, which combine the advantages of two worlds; the inorganic part builds a robust substrate while organic functions make them alive in a way that they can be potentially used in a number of applications. In this tutorial review, we provide an overview of how mesoporous materials are synthesised via the ‘soft template’ path and how the incorporation of organic functions can be achieved. Furthermore, a colourful survey full of examples is presented, providing a small overview of field of applications that can potentially benefit from the use of periodic mesoporous organosilicas (PMOs) and related materials.
