Molecular manipulation of acetylbiphenyl with a four-probe-STM — •Frank Eisenhut¹, Corentin Durand², Francesca Moresco¹, Jean Pierre Launay², and Christian Joachim^2,3 — ¹Institute for Materials Science, Max Bergmann Center of Biomaterials, and Center for Advancing Electronics Dresden, TU Dresden, Dresden, Germany — ²GNS & MANA Satellite, CEMES, CNRS, Toulouse, France — ³International Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS), Namiki Tsukuba, Ibaraki, Japan

A low temperature ultrahigh vacuum four-probe scanning tunneling microscope has been used to study acetylbiphenyl (ABP) molecules on Au(111). Supramolecular assemblies of ABP interacting via hydrogen bonds were investigated and the tetrameric structure were controllably moved several nanometers by voltage pulses along the fcc domain of the Au(111) herringbone reconstruction. Meanwhile, scanning with another tip was possible without influencing the manipulation. The investigation is an important step towards the preparation of the first international nano-car race [1].
