Boron-Oxygen Triple Bonds stabilized for the first time ever

16.04.2010
World first: chemists from the University of Würzburg have, for the first time ever, succeeded in creating a stable triple bond between the elements boron and oxygen. This success is reported in the leading journal "Science".

Why is this renowned scientific magazine so enthusiastic about the work of the Würzburg chemists? This is because stable triple bonds have already been realized for almost all chemical elements in the world that theoretically allow a connection of this nature to be established between them - with the exception of boron and oxygen.

Admittedly, triple bonds between boron and oxygen had already been created in the laboratory, but until now this had only been achieved under extreme conditions: the temperatures had to be well below freezing point for this to happen and both elements have to be present as gases - and in the end the triple bond had no enduring stability.

Triple bond stable at room temperature

It is a very different story for Würzburg's chemistry professor Holger Braunschweig and his colleagues Achim Schneider and Dr. Krzysztof Radacki. They have produced, purified, and characterized a stable boron-oxygen triple bond at room temperature in commonly used solvents.

In its purest form, their product exists as a colorless powder. It can withstand temperatures of up to 100 degrees Celsius for many hours. It is not affected by either daylight or UV radiation. Holger Braunschweig concludes: "For the first time ever, science has at its disposal a stable molecule in which a triple bond has been realized between oxygen and boron."

Exciting prospect for basic research

What use will this have? There are no foreseeable applications for the molecule in everyday life as yet. But this newly created boron-oxygen triple bond is an exciting prospect for basic research.

Reactivity studies have already been conducted on the new molecule at Würzburg's Institute of Inorganic Chemistry. The researchers have joined other elements directly to the triple bond and also separated them from it further. How can the molecule be modified? What can be added to it? These questions will also set the agenda for the work that the scientists wish to pursue next.

Holger Braunschweig: recognized boron expert

Holger Braunschweig is a recognized expert in the chemistry of the element boron. His work in this area has recently been acknowledged by the German Research Foundation (DFG): in 2009, he was awarded the Leibniz Prize, which comes with 2.5 million euros in funding and has the reputation of being a kind of "German Nobel Prize".

Boron - a unique element

What is so special about boron? For chemists, this element represents a challenge: it is electron deficient and in a sense craves these particles. It can only satisfy this craving by forming compounds with other elements. "The compounds that boron creates are highly unusual," explains the professor. A leading textbook on inorganic chemistry even devotes a full chapter to this unique element - this alone is indicative of its special status.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
