Abstract
Fluorescence of pyrene-β-cyclodextrin inclusion complexes in silica and titanium-silica stable sols is studied. It is revealed that high fluorescence ability of pyrene in the aforementioned systems is retained due to the binding with β-cyclodextrin. The study of the influence of N,N-dimethylaniline on the fluorescence of complexes shows that, varying the ratio between cyclodextrin and molecules capable of penetrating into its hydrophobic cavity, one may both efficiently encapsulate these molecules or replace some of them with others in titanium-silica sols.
