On-surface synthesis has gradually become a prevalent approach to constructing two-dimensional functional monolayers on various substrates. In the present work, the synthesis of self-assembled monolayers (SAMs) of benzothiazole derivatives was conducted at the liquid/solid interface for the first time. Two kinds of nanostructures were achieved on the highly oriented pyrolytic graphite (HOPG) surface via the condensation reaction between aromatic aldehyde derivatives and 2-aminothiophenol (ATP). The formation of thiazole-based self-assemblies was revealed by scanning tunneling microscopy (STM) and further confirmed by X-ray photoelectron spectroscopy (XPS). The successful synthesis of the benzothiazole derivatives not only extends the scope of on-surface reactions but also can be applied in designing multifunctional SAMs at the interface.
表面合成已逐渐成为在各种基底上构建二维功能单层的一种流行方法。在本工作中，首次在液/固界面上进行了苯并噻唑衍生物的自组装单分子层（SAMs）的合成。通过芳香醛衍生物和 2-氨基噻吩（ATP）之间的缩合反应，在高取向热解石墨（HOPG）表面上获得了两种纳米结构。扫描隧道显微镜（STM）揭示了噻唑基自组装的形成，并通过 X 射线光电子能谱（XPS）进一步证实。苯并噻唑衍生物的成功合成不仅扩展了表面反应的范围，而且可以应用于界面上设计多功能 SAMs。
