The discovery of buckyballs — soccer-ball-shaped molecules of carbon — helped usher in the nanotechnology era. Now, Lai-Sheng Wang’s research group, including Chemistry doctoral students Wei-Li Li and Zachary Piazza, and colleagues from China have shown that boron, carbon’s neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Until now, such a boron structure had only been a theoretical speculation. The researchers dubbed their newfound nanostructure “borospherene.”
Researchers from Brown University, Shanxi University and Tsinghua University in China have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It’s the first experimental evidence that a boron cage structure — previously only a matter of speculation — does indeed exist.
“This is the first time that a boron cage has been observed experimentally,” said Lai-Sheng Wang, a professor of chemistry at Brown who led the team that made the discovery. “As a chemist, finding new molecules and structures is always exciting. The fact that boron has the capacity to form this kind of structure is very interesting.”
