| 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. |
