Coverage of [Mn₆^IIICr^III]³⁺ SMMs on Surfaces Analyzed by Means of Kelvin Probe Force Microscopy — •Aaron Gryzia¹, Armin Brechling¹, Ulrich Heinzmann¹, Veronika Hoeke², and Thorsten Glaser² — ¹Molecular and Surface Physics, Bielefeld University — ²Anorganic Chemistry I, Bielefeld University

[Mn₆^IIICr^III]³⁺ is a Single-Molecule-Magnet and as such consists out of metal centers and organic compounds and ligands. These organic parts are one of the two main properties playing an important role regarding the adsorption of the molecule onto surfaces, such as e.g. mica and HOPG. The other one is the SMM’s charge of 3+. The resulting dipole moment of the SMM layer influences the contact potential difference (CPD). By using FM-KPFM at UHV conditions we are able to determine the CPD of the sample. Furthermore the CPD depends on the interaction of the SMM with the substrate. By achieving molecular resolution inside the adsorbed layers we are able to determine aligning of SMMs in respect to the substrate. In addition we manipulate the adsorption sites in order to increase the order of the SMMs on the surface.
