基于4-乙酰基联苯在Au（111）上的超分子化学
Supramolecular Chemistry Based on 4-Acetylbiphenyl on Au(111)
摘要：
在金表面上，由4-乙酰基联苯分子组成的超分子显示出结构方向性、可重复性和对外部扰动的鲁棒性。我们研究了这些分子在Au（111）表面上的组装，并分析了所观察到的超分子结构是如何通过弱的长程色散力将4-乙酰基联苯分子稳定在一起的。金属吸附原子用作稳定剂。我们的分析提出了创造复杂分子纳米物体的新方法，这些纳米物体最终可以用作扩展层次结构的设备或种子。
英文摘要：
On a gold surface, supramolecules composed of 4-acetylbiphenyl molecules show structural directionality, reproducibility and robustness to external perturbations. We investigate the assembly of those molecules on the Au(111) surface and analyze how the observed supramolecular structures are the result of weak long-range dispersive forces stabilizing the 4-acetylbiphenyl molecules together. Metallic adatoms serve as stabilizing agents. Our analysis suggests new ways of creating complex molecular nano-objects that can eventually be used as devices or as seeds for extended hierarchical structures.
