Decades before nanoscientists zapped graphite with an electrical discharge to make the first carbon nanotubes, synthetic chemists were trying to craft similar, smaller structures in their reaction flasks. But the belt-shaped compounds these chemists were trying to create entirely from fused benzene rings were tough to come by. Chemists observed one such structure fleetingly via mass spectrometry a decade ago, but no one has been able to synthesize and isolate enough of these carbon nanobelts . . .
