Molecular Wheels Need Hubs to Form

Abstract:
A team of chemists has unraveled the process by which a complex nanoscale structure self-assembles, finding that a wheel-shaped molybdenum oxide molecule takes shape with the help of a transient scaffold at its center.

The researchers describe the formation process of these molybdenum oxide wheels in the January 1 issue of Science. Although the basic ingredients needed to spur the self-assembly of the nanowheels were known, the actual mechanism of their growth "was really a complete mystery," says study co-author Lee Cronin, a chemist at the University of Glasgow. "Self-assembly on the nanoscale is so intricate and so complex, we just don't understand it at a key level."
