Metal nanoparticles (NPs) have physicochemical properties which are distinct from both the bulk and molecular metal species, and provide opportunities in fields such as catalysis and sensing. NPs typically require protection of their surface to impede aggregation, but these coatings can also block access to the surface which would be required to take advantage of their unusual properties. Here, we show that alkyl imidazoles can stabilise Pd, Pt, Au, and Ag NPs, and delineate the limits of their synthesis. These ligands provide an intermediate level of surface protection, for which we demonstrate proof‐of‐principle in catalysis and anion binding.

N-官能化咪唑作为催化和阴离子结合中金属纳米颗粒的稳定剂。

金属纳米颗粒（NP）具有不同于块体和分子金属物种的物理化学性质，并为催化和传感等领域提供了机会。纳米粒子通常需要保护其表面以阻止聚集，但这些涂层也可能阻止进入表面，而这需要利用其不寻常的特性。在这里，我们证明烷基咪唑可以稳定 Pd、Pt、Au 和 Ag NP，并描绘了它们合成的极限。这些配体提供了中等水平的表面保护，为此我们证明了催化和阴离子结合的原理验证。
