利用电化学扫描隧道显微术(ECSTM)和循环伏安法,研究了三个半冠醚配体在Au(111)表面上的吸附结构.虽然配体分子的几何结构复杂、对称性较差,但在Au(111)电极表面,均形成了有序的阵列,这是分子-分子间相互作用与分子-基底间相互作用平衡的结果.高分辨率STM图像揭示了有序阵列中分子的内部结构、取向、排列方式等.该研究为通过过渡金属调控的纳米结构制备提供了实验依据.
The adsorption structures of the three semicrystalline ether ligands on the surface of Au (111) were studied by electrochemical scanning tunneling microscopy (ECSTM) and cyclic voltammetry (CV) .Although the ligands have complex geometrical structures and poor symmetry , But an orderly array was formed on the surface of the Au (111) electrode, which was the result of the balance between molecular-molecular interaction and molecular-substrate interaction. The high-resolution STM image revealed that the molecular Internal structure, orientation, arrangement, etc. This study provides an experimental basis for the preparation of nanostructures controlled by transition metal.
