| الوصف: | Cyclo[18]carbon (C18, a molecular carbon allotrope) can be synthesized by dehalogenation of a bromocyclocarbon precursor, C18Br6, in 64% yield, by atomic manipulation on a sodium chloride bilayer on Cu(111) at 5 K, and imaged by high-resolution atomic force microscopy. This method of generating C18gives a higher yield than that reported previously from the cyclocarbon oxide C24O6. The experimental images of C18were compared with simulated images for four theoretical model geometries, including possible bond-angle alternation:D18hcumulene,D9hpolyyne,D9hcumulene, andC9hpolyyne. Cumulenic structures, with (D9h) and without (D18h) bond-angle alternation, can be excluded. Polyynic structures, with (C9h) and without (D9h) bond-angle alternation, both show a good agreement with the experiment and are challenging to differentiate. |
