Annotation	The host-guest interactions between ferrocene and alpha-cyclodextrin (alpha-CD), beta-cyclodextrin (beta-CD), Heptakis(2,6-di-O-methyl)-beta-cyclodextrin (2-beta-CD) and Heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (3-beta-CD) in aqueous DMSO solution were studied by means of cyclic voltammetry. The complex formation constant K was determined in the solutions of various values of the relative permittivity epsilon(r) of DMSO: water mixture. The dependence of K on dielectric properties of the mixtures 3r for all type of cyclodextrin utilized was found. Furthermore, the dependence of K on the cyclodextrin type was also found. As an additional feature the different dependencies of the Gibbs energy of the complex formation, Delta G(CF)(0) for different CDs on the volume ratio of DMSO, phi(DMSO) were observed.
