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
