摘要： 以玻碳电极为基础电极,经静电自组装方法将带负电荷的四磺酸基铁酞菁与带正电荷的含重氮基团的重氮树脂在电极表面进行层-层自组装,然后经紫外光照射,使铁酞菁的磺酸基与重氮树脂的重氮基发生交联反应,使层与层之间的离子键转为共价键,从而使铁酞菁在电极表面形成稳定、有序且处于分子水平的层-层构筑.用UV-Vis和IR光谱表征了组装过程,用CV方法研究了该电极的电化学性能及其对三氯乙酸的电催化还原.同时用计时电流法测定了三氯乙酸通过该类膜的扩散系数.

Abstract: Construction of a highly stable and covalently bonding multilayer film electrode containing iron phthalocyanine was achieved by UV irradiation of ionic self-assembled multilayer films of diazo-resin(DAR) and iron tetrasulfophthalocyanine(FeTsPc). The fabricated processes of the multilayer film electrode were characterized by UV and IR spectra. The modified electrode not only has stable electrochemical behavior but can also catalyze the electroreduction of TCA. Finally, the diffusion coefficient of TCA was also determined by using chronoamperometry.

Key words: Ordered multilayer film, Covalently bonding interaction, Iron phthalocyanine, Trichloroacetic acid, Electrocatalysis
