由于交错、部分重叠或堆叠,分子网络内分子的非平凡排列使结构测定复杂化。我们证明,结合成像和横向操作与扫描隧道显微镜解决了复杂的结构的分子网络在二维中以一种简单的方式。该网络由5,10,15-三(五氟苯基)-咔咯分子在Ag(111)上形成的单层结构,首次实现了单分子精确操作。我们的研究结果揭示了一个瓦状包装的部分重叠的咔咯分子。密度泛函理论计算支持我们的发现。
Non-trivial arrangement of molecules within a molecular network complicates structure determination due to interdigitation, partial overlap, or stacking. We demonstrate that combined imaging and lateral manipulation with a scanning tunneling microscope resolves the intricate structure of a molecular network in two-dimensions in a straightforward manner. The network, formed by a monolayer of 5, 10, 15-tris (pentafluorophenyl)-corrole molecules on Ag (111), is manipulated for the first time with single-molecule precision. Our results reveal a shingle-like packing of partially overlapping corrole molecules. Density functional theory calculations support our findings.
