在金属基体上自组装的烷硫醇单层膜的平衡结构是由分子间链-链和化学吸附底物-头基相互作用的微妙相互作用决定的。为了了解这种相互作用中单个成分的作用，我们研究了在Au和Ag上自组装的联苯和全氟烷基端链烷硫醇单层膜的结构。从NEXAFS， FTIRRAS和XPS测量得出的单层结构特征表明，定向基板-头基团相互作用具有决定性作用。
The equilibrium structure of alkanethiol monolayers self-assembled on metal substrates is determined by a delicate interplay of the intermolecular chain–chain and chemisorptive substrate–head group inter actions. To understand the role of the individual constituents of this interplay, we studied the structure of biphenyl and perfluoroalkyl terminated alkanethiol monolayers self-assembled on Au and Ag. The structural characteristics of the monolayers derived from NEXAFS, FTIRRAS and XPS measurements point to a decisive role of the directional substrate–head group interactions.
