The construction of a polymer from a chain of boron atoms is currently more science fiction than science – this is the dream of Würzburg Chemistry Professor Holger Braunschweig, who has just received a 1.5 million Euro grant to make boron polymers a reality.
Plastic bags from polyethylene, packaging from polystyrene, frying pans with Teflon coatings: everyday life is awash with polymers. Chemically, polymers are long, chain-like molecules with backbones based almost exclusively on carbon (and sometimes silicon) atoms. Other types of polymers are rare.
The team of Chemistry Professor Holger Braunschweig at the Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, have recently set their sights on the production of polymers based on chains of boron atoms. The as-yet-unknown boron polymers are expected to have highly unusual and useful properties – higher electrical conductance than polymers commonly used in the organic electronics industry being just one example.
Proposal to the DFG finds success
Holger Braunschweig's research proposal to the German Research Foundation (DFG) on this topic was successful: For this goal he will receive 1.5 million Euros from the DFG's Reinhart Koselleck program. This program was created to support particularly innovative and risky projects.
With this funding Prof. Braunschweig hopes to develop efficient synthetic strategies to boron polymers. In this respect it is critical to prevent the boron chains from collapsing in on themselves and forming clusters – a tendency that the element boron is famous for. The research team has come up with five promising strategies to form the desired chains. If successful, they will have discovered a fundamentally new class of materials, the potential applications of which could be immense.
Worldwide recognition as boron expert
The Reinhard Koselleck program of the DFG exclusively funds researchers with exceptional scientific track records. Holger Braunschweig is recognized as a worldwide expert in the chemistry of the element boron. His previous work includes a succession of fundamental breakthroughs in this field – including, among others, the synthesis of the first compound with a triple bond between two boron atoms.
For his work, Braunschweig has been distinguished with two ERC Advanced Grants, each coming with 2.5 million Euro of research funding. In 2009 he also received the 2.5 million Euro Leibniz Prize of the DFG.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
