Imaging Molecules in Atomic Force Microscopy with Carbon Monoxide Terminated Tips — •Nikolaj Moll, Leo Gross, Niko Pavliček, Bruno Schuler, and Gerhard Meyer — IBM Research – Zurich, Säumerstrasse 4, CH-8803 Rüschlikon, Switzerland

Using functionalized tips, the atomic resolution of a single organic molecule can be achieved by atomic force microscopy (AFM). We operate in the regime of short-ranged repulsive Pauli forces while the van-der-Waals and electrostatic interactions only add a diffuse attractive background. With atomic manipulation techniques we induce a on-surface transformation of an individual aromatic molecule into a highly strained 10-membered ring. The formation and breaking of the C–C bond is reversible which opens up the entire field of radical chemistry for on-surface reactions by atomic manipulation.
