Abstract:
After exploring for 25 years, scientists have solved the question of how the iconic family of caged-carbon molecules known as buckyballs form.

The results from Florida State University and the National Science Foundation-supported National High Magnetic Field Laboratory, or MagLab, in Tallahassee, Fla., shed fundamental light on the self-assembly of carbon networks. The findings should have important implications for carbon nanotechnology and provide insight into the origin of space fullerenes, which are found throughout the universe.

Decades-old mystery of buckyballs craked by team led by FSU, MagLab researchers

Tallahassee, /fl | Posted on July 31st, 2012

Many people know the buckyball, also known by scientists as buckminsterfullerene, carbon 60 or C60, from the covers of their school chemistry textbooks. Indeed, the molecule represents the iconic image of "chemistry." But how these often highly symmetrical, beautiful molecules with fascinating properties form in the first place has been a mystery for a quarter-century. Despite worldwide investigation since the 1985 discovery of C60, buckminsterfullerene and other, non-spherical C60 molecules — known collectively as fullerenes — have kept their secrets. How? They're born under highly energetic conditions and grow ultra-fast, making them difficult to analyze.

"The difficulty with fullerene formation is that the process is literally over in a flash — it's next to impossible to see how the magic trick of their growth was performed," said Paul Dunk, a doctoral student in chemistry and biochemistry at Florida State and lead author of the work.

In the study, published in the peer-reviewed journal Nature Communications, the scientists describe their ingenious approach to testing how fullerenes grow.

"We started with a paste of pre-existing fullerene molecules mixed with carbon and helium, shot it with a laser, and instead of destroying the fullerenes we were surprised to find they'd actually grown," they wrote. The fullerenes were able to absorb and incorporate carbon from the surrounding gas.

By using fullerenes that contained heavy metal atoms in their centers, the scientists showed that the carbon cages remained closed throughout the process.

"If the cages grew by splitting open, we would have lost the metal atoms, but they always stayed locked inside," Dunk noted.

The researchers worked with a team of MagLab chemists using the lab's 9.4-tesla Fourier transform ion cyclotron resonance mass spectrometer to analyze the dozens of molecular species produced when they shot the fullerene paste with the laser. The instrument works by separating molecules according to their masses, allowing the researchers to identify the types and numbers of atoms in each molecule. The process is used for applications as diverse as identifying oil spills, biomarkers and protein structures.

The buckyball research results will be important for understanding fullerene formation in extraterrestrial environments. Recent reports by NASA showed that crystals of C60 are in orbit around distant suns. This suggests that fullerenes may be more common in the universe than previously thought.

"The results of our study will surely be extremely valuable in deciphering fullerene formation in extraterrestrial environments," said Florida State's Harry Kroto, a Nobel Prize winner for the discovery of C60 and co-author of the current study.

The results also provide fundamental insight into self-assembly of other technologically important carbon nanomaterials such as nanotubes and the new wunderkind of the carbon family, graphene.

Other research collaborators included the CNRS Institute of Materials in France and Nagoya University in Japan.
