The thiolterminated βcyclodextrin derivative(βCDd) was attached to the surface of gold electrode of quartz crystal resonator by selfassembly. The inclusion reactions of αnaphthalenesulfonate and βnaphthalenesulfonate with βCDd were monitored in situ by using quartz crystal microbalance (QCM). The influences of temperature, concentration, and the substituting position on naphthalene nucleus on the inclusion constant(Kin) and the rate constant(ka) were investigated. The relational expressions of Kin and ka were deduced theoretically and were testified by experimental results. The results obtained indicated that the stoichiometry of the inclusion complexes formed is 1:1 for the host βCDd with naphthalenesulfonate, that the inclusion reactions tallied the Langmuir adsorption model, that the substituting position on naphthalene nucleus has great effect on Kin and ka , and that the inclusion behaviors of the two derivatives with substituent at different positions with βCDd show obvious difference.
