Force-induced tautomerization in a single molecule
by J. N. Ladenthin, T. Frederiksen, M. Persson, J. C. Sharp, S. Gawinkowski, J. Waluk, and T. Kumagai
Nat. Chem. (2016)

Heat transfer, electrical potential and light energy are common ways to activate chemical reactions. Applied force is another way, but dedicated studies for such a mechanical activation are limited, and this activation is poorly understood at the single-molecule level. Here, we report force-induced tautomerization in a single porphycene molecule on a Cu(110) surface at 5 K, which is studied by scanning probe microscopy and density functional theory calculations. Force spectroscopy quantifies the force needed to trigger tautomerization with submolecular spatial resolution. The calculations show how the reaction pathway and barrier of tautomerization are modified in the presence of a copper tip and reveal the atomistic origin of the process. Moreover, we demonstrate that a chemically inert tip whose apex is terminated by a xenon atom cannot induce the reaction because of a weak interaction with porphycene and a strong relaxation of xenon on the tip as contact to the molecule is formed.

2 May 2016 – Opening of PhD position – IDEX-DIPC

We announce the opening of a PhD position in theoretical physics on the topic of Dynamical aspects of quantum transport in nanoelectronics, shared between the Theory group of Laboratoire Ondes et Matičre d'Aquitaine (LOMA) from Bordeaux University and French CNRS, and the Theory and Simulation group of Nanoelectronics at the DIPC. The application deadline is 10 June 2016.
