摘要: 以3,4,5-三羟基苯甲酸甲酯为母体,经与11-二茂铁基溴代十一烷进行亲核取代反应合成了3,4,5-三-(11.二茂铁基)十一烷氧基苯甲酸。通过元素分析、核磁共振、傅里叶变换红外及紫外-可见光谱等对产物进行了表征,并利用循环伏安法、线性扫描伏安法、常规脉冲伏安法、计时电流法和计时电量法研究了产物的电化学行为,测定了其电化学参数.结果表明,该二茂铁基两亲分子在DMF溶液中具有良好的氧化还原可逆性,是由扩散控制的可逆过程,且3个二茂铁基团之间没有强相互作用而显示等同的氧化还原活性.

Abstract:

2,3,4-tri-( l 1-ferroncenyl)decyl-l-yloxy benzoic acid was synthesized via the nucleophilic displacement reaction of methyl 3,4,5-trihydroxybenzoate and 11-ferroneenyl-l-bromoundecane. The compound was then characterized by means of elemental analysis, NMR, FT-IR and UV-Vis, etc. Moreover, the electrochemical behaviour of the compound was investigated using the cyclic voltammetry, the linear sweep vohammetry, the normal pulse voltammetry, the chronoampermetry and the chronocoulometry, and the electrochemical parameters of the compound were finally determined. The results indicate that the dendritic amphiphilie molecules in DMF solution exhibit good diffusion-controlled redox reversibility, and that the three ferroncenyl substituents of the compound do not interact strongly with one another but they exhibit similar redox activity.

Key words: ferrocene, dendritic amphiphilie molecule, electrochemical behavior
