The electrochemical behavior of p‐tert‐butyl‐sulfonylcalix[4]arene (SCA) has been investigated by cyclic voltammetry. The results show that there is an irreversible electrochemical oxidative wave when the potential ranges from 0.9 to 1.9 V versus saturated calomel electrode (SCE) in CH 2 Cl 2 at a glassy carbon electrode. The kinetic parameters of the andic wave, such as α, n , k s , D and the diffusion activation energy ( E d ), were discussed. In addition, the interaction of SCA with metal ions at the water‐air interface was also discussed by Langmuir‐Blodgett (LB) techniques. The results confirm that the selectivity of SCA as ligand for Pb 2+ in monomolecular film is very high by complexation action, which provide the foundation that LB film of SCA modified glassy carbon electrode (GCE) as voltammetric sensor to detect trace amounts of Pb 2+ .
