The nucleation process of a nanoparticle requires an environment that stabilizes the initial seed and favors the growth action. In this paper, we present a specific design of growing points for silver nanoparticles based on the well-known affinity of the silver to the chlorine atoms and to aromatic groups by cation-π interactions. [2-(vinylphenyl)ethyl]chloromethylphenylsilane was proposed as growing point of nanoparticles, which has been synthetized and grafted on a polypropylene membrane. Nanoparticles were synthesized by chemically reducing an AgNO₃ solution with NaBH₄ and the so synthesized nanoparticles were also fully characterized. Using DFT-QTAIM calculations a model of the initial seed and a growth mechanism were proposed.

纳米颗粒的成核过程需要稳定初始种子并有利于生长作用的环境。在本文中，我们基于众所周知的银与氯原子和通过阳离子-π相互作用与芳族基团的亲和力，提出了银纳米颗粒生长点的具体设计。提出了[2-（乙烯基苯基）乙基]氯甲基苯基硅烷作为纳米颗粒的生长点，其已经合成并接枝在聚丙烯膜上。通过用NaBH ₄化学还原AgNO ₃溶液来合成纳米颗粒，并且还充分表征了如此合成的纳米颗粒。利用DFT-QTAIM计算，提出了初始种子的模型和生长机理。
