| Popis: | Transparent methyl-modified silica gel is produced by reacting methyltrialkoxysilane or a mixture thereof with a tetraalkoxy-, trialkoxy- or dialkoxysilane other than the methyltrialkoxysilane with a defined quantity of water at a neutral or acidic pH in the presence of a catalytically effective amount of a metal complex soluble in the methyltrialkoxysilane, and aging the resulting hydrolysate sol to form a gel. Self-sustained films of the transparent gel are produced by spreading the hydrolysate sol onto a nonadherent substrate followed by aging or drying. The gel finds use as a host material for doping optically functional molecules. |
