High Resolution Image Download MS PowerPoint Slide Eric Clar’s qualitative ideas for benzenoids are described in application to various novel nanostructures: graphene, edges in graphene, carbon nanotubes, carbon nanocones, and carbon nanotori. The specially singled out most highly aromatic species with Clar structures consisting entirely of aromatic sextets are proposed to be termed “claromatic”. Several such claromatic nanostructures are identified as manifesting special properties. A molecular structural “( h, k )” characterization for benzo/grapheneic nanostructures is shown to link up neatly with Clar’s ideas.
