Thermal restructuring of silica-grafted -CrO2Cl and -VOCl2 species.


The volatile molecular precursors CrO2Cl2 and VOCl3 were grafted to thermally dehydrated silica in order to obtain site-isolated, monopodal ≡SiO-MO(x)Cl(y-1) species (M = V, Cr). Thermal restructuring under dynamic vacuum was investigated up to 450 °C with different spectroscopic techniques (viz., NMR, UV-Vis, IR, Raman and XPS). During this thermal… (More)
