Crosslinked polymers containing covalently attached functional sites with chemical structures related to those present in ILs and having macroscopic properties very similar to the ones of the corresponding bulk ILs can be advantageously applied to the preparation of gold nanoparticles (AuNPs). The size and morphology of the resulting metal nanoparticles (MNPs) can be easily modulated through a proper combination of the synthetic method used for the generation of the NPs and the structural elements of the polymer. Additionally, the resulting supported AuNPs are demonstrated to be stable for at least eight months with the vials open to the atmosphere. Several synthetic methodologies have been studied, as well as different structural parameters for the functional polymers. Those include the chemical nature (anions and cations) and loading of the ionic liquid-like fragments and the morphology of the polymeric matrix. The results obtained show the potential to prepare supported AuNPs with narrow size distributions and small diameters that can have potential interest for application in different fields.
可以将具有共价键合的功能基团的交联聚合物，其化学结构与离子液体中的结构相关，并且具有与相应的大块离子液体非常相似的宏观性质，应用于金纳米粒子 (AuNPs) 的制备中。所得金属纳米粒子 (MNPs) 的尺寸和形态可以通过合理组合用于生成 NPs 的合成方法和聚合物的结构单元来轻松调节。此外，在将小瓶暴露于大气中打开的情况下，所得负载的 AuNPs 至少稳定八个月。已经研究了几种合成方法以及功能聚合物的不同结构参数。这些包括化学性质（阴离子和阳离子）和离子液体样片段的负载以及聚合物基质的形态。所获得的结果表明有潜力制备具有窄尺寸分布和小直径的负载 AuNPs，这可能对应用于不同领域具有潜在的兴趣。
