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.
