09/2024 Imaging adsorption sites of organic molecules by an adaptive tunnelling current feedback
An automation method for AFM imaging that provides in a single image both, submolecular resolution on organic molecules and atomic resolution on the surrounding metallic surface has been developed. The method is based on an adaptive tunnelling current feedback system that is regulated according to the response of the AFM observables, which guarantees that both the molecules and the surface atoms are imaged under optimum conditions. This facilitates statistical analysis of molecular adsorption geometries and could in the future contribute to autonomous AFM imaging as it adapts the feedback parameters depending on the sample properties.

06/2023 Handmade Molecules: P3N3
On-surface synthesis was used to create the structurally elusive P3N3, an inorganic aromatic analogue of benzene. We report the preparation of this fleetingly existing species on Cu(111) and Au(111) surfaces at 5.2 K through molecular manipulation with unprecedented precision.

05/2023 International Symposium of LOEWE Focus Project "PriOSS"
From May 8 to 10, 2023 the first international symposium of the LOEWE focus group PriOSS “Principles of On-Surface Synthesis” took place in Schloss Rauischholzhausen. During the three symposium days over 60 participants discussed their recent research results in the field of on-surface synthesis, which is a multidisciplinary field encompassing physicist, chemists as well as material scientists. New strategies for the design of new organic nanomaterials with unique properties as well as new characterization methods were presented.
10/2022 "ERC Synergy Grant for PriOSS chemist Michael Gottfried"
European Research Council funds search for unusual ring-shaped carbon compounds for applications in organic electronics
Prof. Dr. Michael Gottfried from the University of Marburg has received an ERC Synergy Grant from the European Research Council (ERC) together with Prof. Dr. Michael Mastalerz from the University of Heidelberg and Prof. Dr. Holger Bettinger from the University of Tübingen. With their project "Tackling the Cyclacene Challenge" (TACY), the three researchers are pursuing the goal of generating a special class of ring-shaped carbon compounds - the cyclacenes - for the first time. The European Research Council is funding the project with around 11 million euros. Of this, around 4.5 million euros is earmarked for the research work at Philipps-Universität Marburg.

09/2021 "Handmade Nanoarchitectures"
In a recent paper in Nature Chemistry we show how to build nanostructures using individual organic molecules one by one with an atomic force microscope. This opens the path to prototyping of new molecular structures, otherwise impossible to fabricate.
