A multi-dentate amphiphilic compound, 3,3'-(dodecylazanediyl)-bis-[N-(2-aminoethyl)propanamide] (12C-2NH2) has been synthesized. The molecular structure was characterized by Fourier transform infrared (FT-IR) spectroscopy, ultraviolet-visible (UV-vis) spectra, nuclear magnetic resonance (NMR) spectra, and fast atom bombardment mass (FAB-MS) spectra. 12C-2NH2 was employed to stabilize silver nanoparticles. Surface properties and stability of silver nanoparticles were controlled by adjusting the 12C-2NH2 to silver (0) molar ratio. 12C-2NH2 was also applied to transfer silver nanoparticles from an aqueous to an organic phase. The transfer efficiency depends on 12C-2NH2 concentration. When 12C-2NH2 to silver (0) molar ratio was 2:1, the highest efficiency of phase transfer to toluene was obtained. These 12C-2NH2 stabilized silver nanoparticles are very stable over a period of four days in toluene.
已合成了一种多齿两亲化合物3,3'-(十二烷基氮杂二亚基)-双-N-(2-氨基乙基)丙酰胺。通过傅里叶变换红外(FT-IR)光谱、紫外可见(UV-vis)光谱、核磁共振(NMR)光谱和快原子轰击质谱(FAB-MS)光谱对其分子结构进行了表征。12C-2NH2用于稳定银纳米颗粒。通过调节12C-2NH2与银(0)的摩尔比来控制银纳米颗粒的表面性质和稳定性。12C-2NH2还用于将银纳米颗粒从水相转移到有机相。转移效率取决于12C-2NH2的浓度。当12C-2NH2与银(0)的摩尔比为2:1时，获得了向甲苯转移的最高效率。这些12C-2NH2稳定的银纳米颗粒在甲苯中四天内非常稳定。
