【Abstract】 Novel 0 and 1 generation multi-headed dendrimer surfactants, based on dedocylamine, were synthesized. The molecular structures were characterized by IR, UV-vis, NMR and FAB-MS. They have good solubility in water and high surface activity. The 12-0G modified silver nanoparticles could be transferred from water to organic phase with high efficiency. The transference is the concentration of novel dendrimer surfactant dependent. In the solvent toluene, these silver nanoparticals are very stable and do not grow or aggregate over a period of several days and the solid product is antioxidation even exposed to air at high temperature. The diameter of silver nanoparticles is about 7nm.更多还原
