INCLUSION CHEMISTRY IN PERIODIC MESOPOROUS HOSTS

This review provides an overview of different aspects of inclusion che mistry in ordered mesoporous host materials such as MCM-41 or MCM-48 ( Mobil codes). A rich field of inclusion chemistry has been explored in this context, including sorption, ion exchange, imbibition followed b y reduction, grafting of reactive metal alkoxides, halides etc., graft ing of silane coupling agents (sometimes followed by subsequent reacti ons), grafting of reactive metal complexes, and polymerization in the channels. Finally, co-condensation of reactive species during the meso pore synthesis is a method to incorporate functionality into the walls of the channel system. Important applications of these modified and f unctionalized systems are heterogeneous catalysis and photocatalysis i nvolving bulky grafted catalysts and/or the conversion of large substr ates. Other potential applications include ion exchange and separation s, removal of heavy metals, chromatography, stabilization of quantum w ires, stabilization of dyes, and polymer composites.
