wpj104@56.com 1 From Microporous to Mesoporous Molecular Sieve Materials and Their Use in Catalysis Avelino Corma 2 Silica-Based Mesoporous Organic¨CInorganic Hybrid Materials Frank Hoffmann, Maximilian Cornelius, Jrgen Morell, and Michael Frba Mesoporous organic¨Cinorganic 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.
