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.
在金表面，由4-乙酰基联苯分子组成的超分子表现出结构方向性、可重复性以及对外部扰动的稳健性。我们研究了这些分子在Au(111)表面的组装，并分析了所观察到的超分子结构是如何由稳定4-乙酰基联苯分子在一起的弱长程色散力导致的。金属吸附原子起到稳定剂的作用。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被用作器件或扩展层次结构的种子。
