| 摘 要： | 利用自组装技术将席夫碱硫醇衍生物在金表面形成自组装单分子膜,并初步研究了此自组装单分子膜的电化学行为,发现该席夫碱分子在0.1 mol?L－1的KCl溶液中具有电化学不可逆氧化还原行为，且随着自组装时间的增加表观电极反应速率常数值显著减小,最后减小为0,并对此进行了解释.

| Abstract: | The gold electrode was modified with a derivative compound of Schiff base. Cyclic voltammetric technique was used to investigate the electrochemical behavior of the electrode. An electrochemical irreversible reduction/oxidation process of the schiff base molecule in 0.1 mol?L－1 KCl solution was found. Electrochemical study shows that the apparent electron-transfer rate constant (kapp) decreases with the increasing of assembled time. Considering the effecting factors on the apparent electron-transfer rate, we deduced that the main factor effecting Schiff bases electrochemical behavior is the interaction force between the Schiff bases molecules. This interaction affects the changing of structure during the electrochemical redox process. |
