Abstract

Using a combination of UHV-STM and molecular mechanics calculations, we investigate the surface self-assembly of a complex multi-component metal-molecule system with synergistic non-covalent interactions. Hydrogen bonding between three-dimensional Lander-DAT molecules and planar PTCDI molecules, adsorbed closer to the surface, is found to be facilitated by electrostatic interactions between co-adsorbed Ni adatoms and the flexible molecular DAT groups.

摘要

利用超高真空扫描隧道显微镜和分子力学计算的组合，我们研究了具有协同非共价相互作用的复杂多组分金属-分子体系的表面自组装。研究发现，吸附在靠近表面的三维 Lander-DAT 分子和平面 PTCDI 分子之间的氢键通过共吸附的 Ni 原子和柔性 DAT 分子之间的静电相互作用得到促进。
