The evolution of a low coverage of benzenethiol molecules on Cu(111) during annealing shows the prevalence of S...H hydrogen bonds involving hydrogen atoms in the ortho position. The row and pattern formation of (methylated) anthracenethiols indicates intermolecular interactions in which hydrogen atoms at the terminal position of the aromatic moiety dominate. In combination, this leads to the notion that pattern formation in classes of arenethiol molecules is each governed by optimization of the intermolecular interactions of the hydrogen atom at one particular position on the arene. This may provide a general guiding principle for the design of arenethiol films.
在退火过程中，苯硫醇分子在 Cu(111)上的低覆盖率的演变表明，涉及邻位氢原子的 S...H 氢键很普遍。（甲基化）蒽硫醇的行和图案形成表明，分子间相互作用中，芳香部分末端位置的氢原子占主导地位。结合起来，这就提出了这样的观点，即在芳硫醇分子的类别中，图案的形成是由优化芳环上一个特定位置的氢原子的分子间相互作用来控制的。这可能为芳硫醇薄膜的设计提供一个普遍的指导原则。
