Abstract

A double-chain structure was fabricated on Au (111) with a bromine-functionalized phenanthroline precursor. We reveal the competition between the on-surface metal-ligand coordination and C-C coupling of the precursor by scanning tunneling microscopy (STM) imaging and density functional theory (DFT) calculations at the molecular level. Our work provides an additional strategy for controlling the on-surface polymerization, which is of great relevance to the construction of novel nanostructures.

摘要

在 Au（111）表面上使用溴功能化菲咯啉前体制备了双链结构。我们通过扫描隧道显微镜（STM）成像和分子水平上的密度泛函理论（DFT）计算揭示了前体表面金属-配体配位和 C-C 键偶联之间的竞争。我们的工作为控制表面聚合提供了一种额外的策略，这对于构建新型纳米结构具有重要意义。
