The Electrochemical Behavior of a N-containing Calix[4]arene Derivative

The electrochemical behavior of 5,11,17,23-Tetrakis-dimethylaminomethylcalix[4]arene (DCA) has been investigated by cyclic voltammetry (CV). The results show that there is an irreversible electrochemical oxidative wave with peak potential of 1.35 V in chloroform at a glassy carbon electrode. The kinetic parameters of the andic wave, such as α, n and ks, were discussed. In addition, a new pair of quasi-reversible redox peaks with peak potentials of 0.72 V and 0.94 V was found. It can result in DCA electrodeposition at the electrode surface. This film modified electrode was characterized by CV and electrochemical impedance spectroscopy (EIS). Moreover, the possible mechanism of electrodeposition was also discussed
