説明:

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 AuSix/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 formation and dissociation of a Si–O bond. This finding may pave the way for advancements in molecular spintronics.
