Until now, scientists were only able to infer molecular structures. Using atomic force microscopy, the individual atomic bonds — each a few ten-millionths of a millimeter long – that connect the carbon molecule’s 26 carbon and 14 hydrogen atoms are clearly visible. The results are reported online May 30 in Science.

The team initially set out to precisely assemble nanostructures made from graphene, a single-layer material in which carbon atoms are arranged in repeating, hexagonal patterns. Building the carbon honeycombs required rearranging atoms from a linear chain into the six-sided shapes; the reaction can p...
