Goldnanoparticles (1.5-1.7 nm) were prepared by use of three tripod thioether oligomers as stabilizing molecules. The particle sizes were independent of the sizes of the stabilizers, and were smaller than those stabilized with simpler thioethers. Molecular dynamics simulations were performed to examine how the stabilizers adsorb on the nanoparticles. Parameters were developed for modeling the interactions
金纳米粒子 (1.5-1.7 nm) 是通过使用三个三脚架硫醚低聚物作为稳定分子来制备的。颗粒尺寸与稳定剂的尺寸无关,并且比用更简单的硫醚稳定的颗粒尺寸小。进行分子动力学模拟以检查稳定剂如何吸附在纳米颗粒上。开发了用于模拟金和有机分子之间相互作用的参数。在 300 K 的显式氯仿溶剂中的模拟揭示了稳定剂在纳米颗粒上的多点吸附。
