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.

For more information please consult the announcement posted at http://dipc.ehu.es/join_us.php.


16 March 2016 – Student internships available at the DIPC

If you are interested in a paid internship in Donostia-San Sebastián during your university studies and want to know the world of research, we have a number of exciting projects in nanoscience, physics and chemistry at the DIPC that may interest you. Check out http://internships.dipc.org.


22 February 2016 – Towards Reality in Modelling of Molecular Electronics (TRMME)

We are organizing the international workshop Towards Reality in Modelling of Molecular Electronics (TRMME) that will take place in San Sebastián, Spain, on June 13-17, 2016.


9 January 2015 – Journal of Physics: Condensed Matter

I joined the Advisory Board of Journal of Physics: Condensed Matter, covering the whole of condensed matter physics including soft condensed matter and nanostructures with experimental, theoretical and computational studies. Looking forward to help shaping the strategy of this high quality journal. Check out also the new physics blog JPhys+ from IOP Publishing.
