"Grossly Warped Nanographene" Twists Graphene into Another Dimension
The grossly warped nanographene consists of 80 carbon atoms joined together in a network of 26 rings, with 30 hydrogen atoms on the outside rim.
In contrast to graphene sheets, which typically have planar two-dimensional geometries, the new material juts out from a single plane because of the five 7-membered rings and one 5-membered ring embedded in the hexagonal lattice of carbon atoms.
Pushing its geometry out of planarity has altered the new material’s physical, optical, and electronic properties vis-à-vis its carbon cousins.
“Our new grossly warped nanographene is dramatically more soluble than a planar nanographene of comparable size,” said Lawrence T. Scott, professor at Boston College and one of the principal authors of the research, in a press release. “The two differ significantly in color, as well. Electrochemical measurements revealed that the planar and the warped nanographenes are equally easily oxidized, but the warped nanographene is more difficult to reduce.”
