利用X射线吸收光谱（XAS）和X射线光电子能谱（XPS）对表面附着在Au（111）上的轮烷进行了表征。单分子层由蒽塞的硫醇线、通过将硫醇与二苯并-24-冠-8和含二硫化物的[3]轮烷混合获得的假轮烷制备。XAS和XPS表现出明显的区别之间的单分子膜，允许识别光谱的贡献从表面附着的轮烷的单独的组件。光谱数据清楚地表明，只有[3]轮烷给出了所需的金结合的联锁分子。
X-ray absorption spectroscopy (XAS) and X-ray photoemission spectroscopy (XPS) were utilized to characterize a surface-attached rotaxane on Au(111). Monolayers were prepared from an anthracene-stoppered thiol thread, a pseudorotaxane obtained by mixing the thiol with dibenzo-24-crown-8 and a disulfide-containing [3]rotaxane. XAS and XPS showed clear distinctions between the monolayers, allowing identification of spectral contributions from the separate components of the surface-attached rotaxane. Spectroscopic data clearly showed that only the [3]rotaxane gave the desired gold-bound interlocking molecule.
