Spin States of Trioxotriangulene Controlled by Si-O Bond Formation and Dissociation on AuSi_<i>x</i> Surfaces.

ABSTRACT: The radical molecules have attracted significant attention from researchers because their electronic and spin properties can be controlled via the structure and heteroatoms. With the advancements in on-surface synthesis, it has become possible to conduct spin engineering at the single-molecule level. Here, we investigate the controllable polarized and electronic states of 4,8,12-trioxotriangulene adsorbed on AuSi_x/Au(111) surfaces with a combination of scanning tunneling microscopy (STM) operated at 4.3 K and density functional theory calculations. A rich variety of STM topographic contrasts of the molecule reveals various interactions between the molecule and the substrate. We found that the magnetic and electronic properties can be modulated through tip-induced formatio
