Exploring the characteristic “plug-in” configuration of an adsorbed starburst molecule

Abstract

In this study, the adsorption of starburst molecules (C57H48N4, SBM) deposited on Au(111) was investigated by scanning tunneling microscopy (STM). SBM molecules selectively adsorb on the face-centered-cubic regions of Au(111) in quasi one-dimensional chains. Compared with the SBM structure on hBN/Rh(111), the assembly structure of SBM on Au(111) can be clearly confirmed to be molecular chains in the “plug-in” configuration. Scanning tunneling spectroscopy (STS) revealed that the interaction between SBM molecules and Au(111) induces the modification of the molecular electronic states. The STS mapping further revealed a continuous 1D electronic state concentrated at the center of the SBM molecular chains.
