Abstract
We have used fluorescent spectroscopy and laser flash photolysis to investigate the photonics of pyrene molecules in a pyrene-β-cyclodextrin inclusion complex in various media. We have observed a protective effect of β-cyclodextrin relative to solubilized pyrene molecules during quenching of fluorescence by Ti ions (or titanium dioxide particles) in mixed colloids. In the presence of a precursor of silica (a TEOS solution), the pyrene molecules react with the colloidal silica particles formed, and the reaction is accompanied by decomposition of the pyrene-β-cyclodextrin inclusion complex and efficient photoionization of pyrene. ©2001 Plenum Publishing Corporation.
