Over recent years, the field of thiolate-protected gold nanoclusters has made remarkable progress. The successful determination of the structure of some of these clusters by X-ray crystallography was a milestone in this field. X-ray crystallography is arguably the most important technique in the field up to now, and it enabled the study of structure evolution as a function of cluster size. It also shed light on the structure of the Au–S interface. Recently, it has been realized that thiolate-protected gold clusters are very dynamic systems. Metal atoms and ligands can exchange easily between clusters. Furthermore, the adsorbed ligands bear conformational dynamics. Such dynamic effects call for experimental methods that can cope with it.

硫醇盐保护的金纳米团簇的振动特性

近年来，硫醇盐保护的金纳米团簇领域取得了长足的进步。通过X射线晶体学成功确定其中一些团簇的结构是该领域的一个里程碑。X射线晶体学可以说是迄今为止该领域最重要的技术，它使研究结构演化与团簇尺寸有关成为可能。它还阐明了Au-S界面的结构。最近，已经认识到硫醇盐保护的金簇是非常动态的系统。金属原子和配体可以很容易地在簇之间交换。此外，吸附的配体具有构象动力学。这种动态影响需要实验方法来应对。
