已经开发出一种模块化系统，可以将分子以良好控制的几何形状垂直安装到金属表面上。该方法基于具有亲电子中心的反应平台（三氮杂三角鎓盐）。功能分子通过 C-C 键形成连接。与表面的距离可以通过垫片来改变，并且功能单元彼此之间的距离可以通过平台的尺寸来改变。母体三氮杂鎓盐以及 Au(111) 表面上的功能化平台的自组装产生了稳定的六角有序吸附层。
A modular system has been developed to mount molecules upright onto metal surfaces in a well controlled geometry. The approach is based on a reactive platform (triazatriangulenium salt) with an electrophilic center. Functional molecules are attached via C-C bond formation. The distance from the surface can be varied by a spacer, and the distance of the functional units from each other by the size of the platform. Self-assembly of the parent triazaangulenium salt as welt as the functionalized platforms on Au(111) surfaces results in stable, hexagonally ordered adlayers.
