| 中文摘要 | multilayers of anionic phosphotungstic acid (pta) clusters and positively charged protonated poly(allylamine hydrochloride) (pah) were assembled by layer-by-layer self-assembled method on au electrode modified by 3-mercaptopropionic acid (3-mpa). the effect of the charge of the surface of the multilayer assembly on the kinetics of the charge transfer reaction was studied by using the redox probes [fe(cn)(6)](3-)/(4-) [ru(nh3)(6)](2+/3+). the cyclic voltammetry experiments showed that the peak currents and peak-to-peak potential differences changed after assembling different layers on the electrode surface indicating that the charge of the surface has a significant effect on the kinetics of the studied charge transfer reactions. these reactions were studied in more detail by electrochemical impedance spectroscopy. when [fe(cn)(6)](3-/-) was used as the redox label, multilayers that terminated with negatively charged pta showed a high charge transfer resistance but multilayers that terminated with positively charged pah showed lower charge transfer resistance. with [ru(nh3)(6)](2+/3+) as the redox label, the charge transfer resistance at multilayers that terminated with positively charged pah was much higher than at the multilayer terminated by the negatively charged pta. |
