The adsorption and assembly of pristine Salen molecules have been investigated by low-temperature scanning tunneling microscopy (STM) on Au(111), Ag(111) and Cu(111). High-resolution STM imaging reveals that the Salen molecules form three types of conformational isomers and several self-assembled unit structures on Au(111) and Ag(111). However, the morphology, proportional distribution and self-assembled structure of Salen on Cu(111) are different from those on Au(111) and Ag(111) because the Cu(111) substrate invokes a relatively stronger molecule-substrate interaction. This study demonstrates that the conformational changes of the pristine Salen molecule can be mediated by the underlying substrate lattice structure, leading to subsequent formation of self-assembled structures on the surface.

铸币上原始Salen分子的表面介导有序

已通过低温扫描隧道显微镜（STM）在Au（111），Ag（111）和Cu（111）上研究了原始Salen分子的吸附和组装。高分辨率STM成像显示，Salen分子在Au（111）和Ag（111）上形成三种类型的构象异构体和几个自组装的单元结构。但是，Salen在Cu（111）上的形态，比例分布和自组装结构与Au（111）和Ag（111）上的不同，因为Cu（111）底物引起了相对较强的分子-底物相互作用。这项研究表明原始Salen分子的构象变化可以由下面的底物晶格结构介导，导致随后在表面上形成自组装结构。
