Abstract

This study presents an innovative synthesis of dihydrotetraazapentacene (DHTAP) and the scanning tunneling microscopy (STM) investigation of the initial stages of its growth on Au(111). We were able to demonstrate that, up to the fourth monolayer, the DHTAP films show a high structural order and growths in perfect epitaxy. This behavior can be unequivocally attributed to the stabilizing effect of intralayer hydrogen bonding interactions.

摘要

本研究展示了二氢四氮杂并五苯（DHTAP）的创新合成方法以及对其在Au(111)上生长初期的扫描隧道显微镜（STM）研究。我们能够证明，直至第四个单分子层，DHTAP薄膜都呈现出高度的结构有序性，并以完美的外延方式生长。这种行为可以明确归因于层内氢键相互作用的稳定作用。
