3,4-二羟基苯甲酸在自组装结构中的电化学行为

Electrochemical Behavior of 3,4 Dihydroxybenzoic Acid in Self Assembled Monolayer Electrode System

电极与有确定取向的电活性基团之间的电子传递是电化学领域的研究热点．利用二维有序薄膜固定电活性官能团是一个成熟的方法［１］，主要包括ＬＢ技术和自组装技术，这两者都存在着样品合成困难的问题．近年来，通过表面逐层反应来固定电活性官能团已有研究，但是反应过程...

The self assembled monolayer of cystamine was prepared on gold electrode and 3,4 dihydroxybenzoic acid(DHBA) was electrochemically deposited on cystamine surface as a functional group by electrostatic adsorption, namely, molecular deposition. It shows that the MD/SAM structure has a higher stability, and E 1/2 of the DBAH in MD/SAM shifts more negative than that of on naked gold electrode. The n decanethiol was also used to fill defects in MD/SAM, it results in much better cyclic voltermmetric behavior.
