| In this work, we show that dispersed Au nanoparticles (AuNPs) having diameters of less than 3 nm can be obtained with DAB-ferrocenyl dendrimers. [1],[2],[3],[4][5] Dendrimers of first, third and fifth generation have been studied and good dispersed non aggregated nanoparticles were obtained in all the cases. In a similar way than in homogeneous media[6], Au nanoparticles inter-dendritic have been obtained when first or third generation dendrimer modified electrodes were used, while smaller nanoparticles were obtained with fifth generation dendrimer, indicating that Au nanoparticles intra-dendritic have been syntethized. The AuNPs were obtained from a HAuCl4 solution and subsequent chemical reduction with NaBH 4. The ferrocene groups were previously electro-oxidized to avoid the direct reduction of Au (III) by the ferrocenyl groups.[7] The formation of AuNPs was followed by UV-Vis spectrophotometry. The electrochemical behaviour of these electrodes has been studied. | |
