用循环伏安法（CV）和电化学扫描隧道显微镜（ECSTM）研究了4-硝基苯胺（4-NA）与多环芳烃（芘、芘）在Au（111）表面的共吸附结构. 4-NA分子可以形成具有表面手性的六重对称网络。氢键在这种结构的形成中起着重要的作用。由三角形和正方形单元包围的六边形孔可以作为容纳芘和苝的模板。本研究结果为主客体在固/液界面的共组装过程提供了直接证据。
The co-adsorption structures of 4-nitroaniline (4-NA) and polycyclic aromatic molecules, such as pyrene and perylene, on Au(111) surface have been investigated by cyclic voltammetry (CV) and electrochemical scanning tunneling microscopy (ECSTM). 4-NA molecules can form six-fold symmetry networks with surface chirality. Hydrogen bond plays an important role in the formation of this structure. The hexagonal porous enclosed by triangle and square units can serve as a template for the accommodation of pyrene and perylene. The present result provides direct evidence for the host–guest coassembly process at the solid/liquid interfaces.
