α-Cyclodextrin (α-CD) inclusion compounds containing the carboxylic acids (octanoic, decanoic, lauric or dodecanoic, myristic or tetradecanoic, palmitic or hexadecanoic and stearic or octadecanoic) as guests were synthesized and applied for preferential adhesion of silver nanoparticles (AgNPs). The binding affinity depends of the chain length of the respective guest and is most efficient for octanoic and decanoic acids. The immobilization of nanoparticles is caused by the spatial replacing of the stabilized shell of the nanoparticles by COOH groups of the guests molecules, located at the entrance of cavity of α-CD, corresponding to the 001} crystal plane. Crystalline coating with nanoparticles provides a means of storing of AgNPs on solids state without aggregation. The stabilization of the particles on the surface is valid for a given length and ordering of the guest in the cavities of the α-CD being the octanoic and decanoic acid the most appropriated.

银纳米粒子(AgNPs)。结合亲和力取决于各自客体的链长,
辛酸和
癸酸的结合亲和力最强。纳米粒子的固定化是由于客体分子的 COOH 基团取代了纳米粒子的稳定外壳,客体分子位于 α-CD 的空腔入口处,与 001} 晶面相对应。纳米粒子的晶体涂层为 AgNPs 提供了一种在固体状态下存储而不会聚集的方法。在α-CD空腔中的客体的特定长度和排序条件下,颗粒在表面的稳定性是有效的,其中
辛酸和
癸酸最为合适。
