β‐Cyclodextrin (CD)‐modified poly‐ N ‐acetylaniline (PNAANI) electrode is used to study the redox reaction of thymine. The characteristics of a supramolecular inclusion complex between β‐CD and thymine is examined. The mechanism of thymine oxidation is proposed. A nontoxic, stable, and convenient method of square‐wave voltammetry for the measurement of thymine in the concentration range of 2.5×10 −5 mol/L to 1.0×10 −3 mol/L has been developed.
