Polymers based on boron?
(Nanowerk News) 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.
