A diffuse reflectance laser flash photolysis study of solid beta-cyclodextrin inclusion complexes of xanthone and acetoveratrone

The photochemistry of solid beta-cyclodextrin (beta-CD) inclusion complexes of xanthone and acetoveratrone has been studied by steady-state emission s pectroscopy and diffuse reflectance laser flash photolysis (DRLFP). The for mation of beta-CD inclusion complexes of acetoveratrone in aqueous solution has been established by means of steady-state emission spectroscopy. The a nalysis of the guest triplet decay in the solid beta-CD complexes using the Albery model confirms that such a model can provide a better understanding of the inclusion effect in solid cyclodextrin complexes and therefore can help with the understanding of the weak interactions in supramolecular chem istry.
