Functional groups in the molecule play an important role in the molecular organization process. To reveal the influence of functional groups on the self-assembly at interface, herein, the self-assembly structures of three liquid crystal molecules, which only differ in the functional groups, are explicitly characterized by using scanning tunneling microscopy (STM). The high-resolution STM images demonstrate
分子中的官能团在分子组织过程中起重要作用。为了揭示官能团对界面处的自组装的影响,在此,通过使用扫描隧道显微镜(STM)来明确表征仅三个官能团不同的三个液晶分子的自组装结构。高分辨率STM图像显示了三个液晶分子的超分子组装结构之间的差异,这归因于氢键相互作用和π - π不同功能组之间的堆叠交互。密度泛函理论(DFT)的结果也证实了这些官能团对自组装的影响。在界面上自组装液晶分子的努力可以增强对超分子组装机理的理解,并有利于液晶的进一步应用。
