Pretty with a twist
2020-01-16 – Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. Scientists at the Technical University of Munich (TUM) have functionalized a simple rod-like building block with hydroxamic acids at both ends. They form molecular networks that not only display the complexity and beauty of mono-component self-assembly on surfaces; they also exhibit exceptional properties.
Switching with molecules
2018-05-24 – A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
Complex tessellations, extraordinary materials
2018-01-22 – An international team of researchers lead by the Physics Department at TUM has discovered a reaction path that produces exotic layers with semiregular structures. These kinds of materials are interesting because they frequently possess extraordinary properties. In the process, simple organic molecules are converted to larger units which form the complex, semiregular patterns.
Prestigious ERC grants for research projects in physics
2017-09-05 – Two young scientists at TUM’s physics department will receive Starting Grants from the European Research Council (ERC). In addition a full professor is awarded a Proof of Concept Grant. Each of the three research fields at the department – Biophysics, Condensed Matter Physics and Nuclear, Particle and Astrophysics – has recieved one of the prestigious awards.
Tiny works of art with great potential
2016-07-14 – Unlike classical crystals, quasicrystals do not comprise periodic units, even though they do have a superordinate structure. The formation of the fascinating mosaics that they produce is barely understood. In the context of an international collaborative effort, researchers at the Technical University of Munich (TUM) have now presented a methodology that allows the production of two-dimensional quasicrystals from metal organic networks, opening the door to the development of promising new materials.
Molecular architectures see the light
2016-03-02 – Organic photovoltaics bear great potential for large-scale, cost-effective solar power generation. One challenge to be surmounted is the poor ordering of the thin layers on top of the electrodes. Utilizing self-assembly on atomically flat, transparent substrates, a team of scientists at Physics Department of (TUM) has engineered ordered monolayers of molecular networks with photovoltaic responses. The findings open up intriguing possibilities for the bottom-up fabrication of optoelectronic devices with molecular precision.
2012-01-12 – Die Miniaturisierung in der Elektronik haben jetzt ein Physikerteam um Dr. Willi Auwärter und Professor Johannes Barth ins Extreme getrieben. Sie präsentieren einen neuartigen molekularen Schalter dessen Funktionsweise auf der Position eines einzelnen Protons in einem Porphyrinring mit einem Innendurchmesser von weniger als einem halben Nanometer basiert.
