Abstract

The reduction of N-(p-fluorobenzenesulfonyl)phthalimide on polycrystalline gold and Au(111) was studied. Our key finding is the decomposition of the compound on the surface, leaving only sulfur behind. This was supported by X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV) and scanning tunneling microscopy (STM). The modification leads to observation by STM of well-known as well as new phases for the S modified Au(111) surface.

摘要

我们研究了 N-(对氟苯磺酰基)邻苯二甲酰亚胺在多晶金和 Au(111)表面上的还原反应。我们的主要发现是该化合物在表面上发生分解，只留下硫。X 射线光电子能谱（XPS）、循环伏安法（CV）和扫描隧道显微镜（STM）都支持这一发现。这种修饰导致了通过 STM 对 S 修饰的 Au(111)表面的一些已知相和新相的观察。
