| Abstract: | A new water-soluble glycodendrimer containing 9 terminal modified xylose branches was prepared from nona-azide terminated dendrimer by ‘click’ chemistry. The glycodendrimer was analyzed by 1H, 13C NMR and mass spectroscopy and used to stabilize palladium (PdNPs) and platine (PtNPs) nanoparticles. These DSN are stable in water and were characterized by TEM. The platinum NPs showed a remarkable catalytically activity for olefin hydrogenation in water at room temperature. |
