Abstract: The molecular carbon allotropes have an enduring attraction to chemists and physicists for their elusive structures and extraordinary properties. Cyclo[16]carbon has been produced on the surface and is well characterized, while, it is interesting that molecular carbon allotrope, like C16, referring to molecules composed of 16 carbon atoms, presents a fascinating realm of isomeric possibilities. Except for cyclo[16]carbon, C16 isomers with other structures have been only predicted by theory. Here, we report the synthesis and structural characterization of a graphene-shaped isomer, i.e., C16 flake on a bilayer NaCl surface grown on Au(111), using an atom-manipulation strategy by eliminating chlorine from a fully chlorinated pyrene molecule, C16Cl10. Characterization of such a C16 flake by bond-resolved atomic force microscopy revealed an sp- and sp2-hybridized structure.
