How to control single-molecule rotation.
TL;DR: The authors use the electric field from a scanning tunneling microscope tip to precisely induce unidirectional rotation of a polar molecule, allowing visualization of the molecule’s internal dipole moment.
New class of metal bound molecular switches involving H-tautomerism.
Grant J. Simpson,Simon William Leslie Hogan,Marco Caffio,Christopher J. Adams,Herbert A. Früchtl,Tanja van Mourik,Renald Schaub +6 more
TL;DR: The present work reveals how H-tautomerism is the mechanism for switching in substituted quinone derivatives, a novel class of molecules with a different chemical structure, and reveals that the previous restrictions applying to tautomeric molecular switches bound to a surface are not valid in general.
Control of long-distance motion of single molecules on a surface.
Donato Civita,Marek Kolmer,Grant J. Simpson,An-Ping Li,Stefan Hecht,Stefan Hecht,Stefan Hecht,Leonhard Grill +7 more
TL;DR: At cryogenic temperatures, the bias voltage from an STM tip can propel a large organic molecule, dibromoterfluorene, long distances—tens of nanometers along straight tracks on the flat silver surface (see the Perspective by Esch and Lechner).

On-Demand Final State Control of a Surface-Bound Bistable Single Molecule Switch
José A. Garrido Torres,Grant J. Simpson,Christopher J. Adams,Herbert A. Früchtl,Renald Schaub +4 more
TL;DR: In this Letter, it is demonstrated how control of the final state of a surface-supported bistable single molecule switch can be realized and suggested an alternative strategy to achieve final state control in unimolecular bistability switches.
Formation of bioinorganic complexes by the corrosive adsorption of (S)-proline on Ni/Au(111).
Riho T. Seljamäe-Green,Grant J. Simpson,Federico Grillo,John Greenwood,Stephen M. Francis,Renald Schaub,Jerome E. Gano,Herbert A. Früchtl,Paolo Lacovig,Christopher J. Baddeley +9 more
TL;DR: The adsorption of (S)-proline onto Au(111) precovered by two-dimensional nickel nanoclusters was investigated by scanning tunneling microscopy, X-ray photoelectron spectroscopy, and high-resolution electron energy loss spectroscology and two distinguishable forms of nickel prolinate complexes were identified.
