The effect of the concurrent action of intermolecular and molecule–substrate interactions on the two-dimensional (2D) self-assembly of organic molecules on solid surfaces is investigated in a combined experimental and theoretical effort. Scanning tunneling microscopy measurements of terephthalic acid on the Cu(111) surface, a model system where the interplay between the two interactions is particularly evident, are used to develop a general, simple, and computationally inexpensive model that quantitatively accounts for the experimental observations. The model, related to the well-known Frenkel–Kontorova model, offers a comprehensive description of the “subtle interplay” between intermolecular and molecule–substrate interactions and provides a qualitative and quantitative predictive capability in the design and fabrication of 2D molecular nanostructures at surfaces.

量化表面分子组装中分子间和分子-底物相互作用之间的“微妙相互作用”

结合实验和理论研究，研究了分子间和分子-底物相互作用的同时作用对固体表面上有机分子的二维（2D）自组装的影响。对铜（111）表面上的对苯二甲酸的扫描隧道显微镜测量是一个模型系统，其中两个相互作用之间的相互作用特别明显，可用于开发通用，简单且计算便宜的模型，该模型定量地说明了实验观察结果。该模型与著名的Frenkel-Kontorova模型有关，
