Electrochemical behavior of 4‐ tert ‐butylcatechol (H 2 Q) in the presence of β‐cyclodextrin (β‐CD) was studied using cyclic voltammetry and hydrodynamic voltammetry. An electrochemical model in which both H 2 Q and its oxidized form (Q) created inclusion complexes with β‐CD was proposed, and it was concluded that both free (as a result of complex‐dissociation reaction) and complex species could performed electron transfer. The heterogeneous rate constant for electron transfer of the inclusion complexes and their kinetic and thermodynamic parameters were obtained using digital simulation. © 2012 Wiley Periodicals, Inc.
