Donor-Acceptor Properties of a Single-Molecule Altered by On-Surface Complex Formation.

Figure: Structural and Electronic characterization of the fused Donor-Acceptor molecule TTF-dppz by AFM and KPFM.
Electron donor-acceptor molecules are of outstanding interest in molecular electronics and organic solar cells for their intramolecular charge transfer controlled via electrical or optical excitation. The preservation of their electronic character in the ground state upon adsorption on a surface is cardinal for their implementation in such single molecule devices. We investigated by atomic force microscopy and scanning tunneling microscopy a prototypical system consisting of a Pi-conjugated TTF-dppz molecule adsorbed on thin NaCl films on Cu(111). Depending on the adsorption site, the molecule is in a free state or in a bound state. In the latter case the molecule adopts a specific adsorption site leading to the formation of a chelate complex with a single Na+ alkali cation pulled out from the insulating film. By this interaction the charge distribution of the molecule is drastically altered. The chelate complex formation is reversible which allow us to switch between the different states of the molecules.

Thermal control of sequential on-surface transformation of a hydrocarbon
molecule on Cu(111).

Three-step thermally-induced on-surface chemical reaction is demonstrated in this work. With high-resolution atomic force microscopy, we investigate the process in detail from the initial structure to the final produces via direct observation of the molecular structures.

Van der Waals interactions and the limits of isolated atom models at interfaces.



Figure: Paradigmatic van der Waals force measurement with a Xe functionalized tip
Van der Waals forces are among the weakest, yet most decisive interactions governing condensation and aggregation processes and the phase behavior of atomic and molecular matter. Here, we for the first time presented a paradigmatic measurement of van der Waals interactions represented by the noble gas atom pairs Ar-Xe, Kr-Xe and Xe-Xe with a Xe-functionalized tip of an atomic force microscope at low temperature. Individual rare gas atoms were fixed at node sites of a surface-confined two-dimensional metal-organic framework formed on Cu(111). Systematic force measurements established the depths of the potential curves for Xe-Ar, Xe-Kr and Xe-Xe at 18.1, 26.1 and 35.9 meV, respectively, which is in agreement with the expected trend. However, detailed density functional theory calculations revealed that the adsorption induced charge redistribution strengthened the van der Waals forces by a factor of up to two, thus demonstrating the limits of a purely atomic description of the interaction in these representative systems.

Extended Halogen Bonding between Fully Fluorinated Aromatic Molecules.



Figure: Atomic-scale agreement between the AFM measurement and the density functional calculation theory of the supramolecular system
We present a study that a detailed chemical structure of a hydrogen bonded supramolecular system is experimentally measured by high-resolution atomic force microscopy and Kelvin probe force microscopy. The measured structure, including bending, rotation, and tilting of the individual molecule, and the hydrogen bonding between two adjacent molecules, can now be in-depth studied by combination of high resolution AFM and density functional theory calculation at atomic-scale.

See our publications in ACS Nano.



Extended Halogen Bonding between Fully Fluorinated Aromatic Molecules.

High-resolution force microscopy with a functionalized CO tip of an atomic force microscope allows us to observe the chemical structures of molecules. Here, we study the atomic-scale contact between fully fluorinated aromatic molecules on Ag(111) surface at low temperature and present a strong directional bonding in the C-F···F-C contact. While the σ hole is absent at the cap of F, the scheme of the contact has a high similarity to halogen bonding.

See our publications in ACS Nano.

Quantifying the atomic-level mechanics of single long physisorbed molecular chains.

We present a study on in-situ polymerized fluorine chains by pulling individual chains with the tip of an atomic-force microscope at 4.8 K. The measured variations of the force gradient provided detailed insights into the detachment processes of fluorine units and the role of near-incimmensurability with the substrate structure. Extended Frenkel-Kontrova model calculations allow us to estimate the detachment force and desorption energy of the repeat units.

See our publication in PNAS.

Single-Molecule Rotations Controlled by Localized Force Spectroscopy

Figure: Cartoon showing the controlled rotation of a single porphyrin on Cu(111) induced by a single force spectroscopy. STM images are Controlled repositioning of single molecules with a scanning probe microscope is a key step toward understanding their adhesion and frictional properties at the atomic scale. In this work, we applied local mechanical forces at specific areas of the porphyrin structure to induce its rotations on the Cu(111) surface. Three- dimensional force spectroscopy with sub-molecular precision was first employed to chemically recognize the peripheral carbonitrile groups (CN) of the molecule. These extremely small areas (≈100x100 pm2) were then used to attached the AFM tip apex and applied local mechanical forces. In response to these forces, the molecular structure elastically deforms and changes its conformation. Depending on the selection of one of four CN groups, the molecule is either rotated clockwise or counterclockwise in a controlled way. These results emphasize the importance for fundamental studies of mechanical properties and local chemical reactivity of complex molecular structures in order to better understand diffusive processes at the molecular scale. Such systematic studies might also open the way for mechanically driven manipulation techniques or local force- induced chemical reactions (mechano-chemistry) at the atomic scale. This work has been conducted in collaboration with the group of Prof. F. Diederich (ETH Zürich).

3D-force field of single C60 molecules.

In this work, the chemical structure of C60 molecules adsorbed on Cu(111) is resolved by nc-AFM imaging giving a direct and unambiguous observation of their orientations on the surface. Systematic three-dimensional force spectroscopic measurements performed above single C60 molecules reveal that short-range repulsive forcesmost likely originating from Pauli exclusion principle are required to reach such intramolecular resolutions. The detection of site- dependent tip-sample force variations above the buckyball structure is demonstrated at the atomic scale.

See our publications in ACS Nano and the special issue in ncAFM published in J. Phys.: Condens. Matter 1 and J. Phys.: Condens. Matter 2.
