## Description

- description: 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.
