Gold nanoparticles (Au NPs) with tailor‐made structures and properties are highly desirable for applications in catalysis and sensing. In this context, surface modifications of Au NPs are of particular relevance. Herein, we present a sequential surface modification of Au NPs with AgI coordination complexes, which can be converted into Ag0‐doped Au NPs by simple ligand‐exchange reaction. The key innovative
具有量身定制的结构和性能的金纳米颗粒(Au NPs)非常适用于催化和传感应用。在这种情况下,Au NPs的表面修饰特别重要。在本文中,我们介绍了具有Ag I配位配合物的Au NP的顺序表面修饰,可以通过简单的配体交换反应将其转化为Ag 0掺杂的Au NP。这种表面修饰的关键创新元素是基于生物恶唑啉的多功能配体,使配位的Ag I紧密靠近颗粒表面。
