Abstract: Influence of complexation with β-cyclodextrin on photochemical properties of four bisphenols has been investigated. Stoichiometry of the inclusion complexes formed has been found to be 1: 1 and association constants have been calculated from fluorescence experiments. The complexation leads to significant increase in the values of degradation and photoionization quantum yields, which is promising for the development of water decontamination methods.

Keywords: bisphenols, endocrine disruptors, β-cyclodextrin, complexation, photodegradation.
