| Abstract
| - Inclusion complexes of cyclodextrins with organometallic coordination compounds of Pd,Pt, Rh, Fe, Ni, and Ru have been used to produce porous metal−silica hybrid materials.The cyclodextrins are templates for the structure of the silica and lead to a uniform “worm-type” pore system. After the templating step the organometallic compounds can be employedas in situ precursors for the preparation of metal nanoparticles within the pore system,thus leading to a one-step synthesis of silica-supported metal catalysts. These new materialsare characterized and how the chemical confinement of the silica pores can influence thesize, structure, and distribution of the nanoparticles is studied.
