  • The carbon allotrope cyclo[16]carbon has been synthesized using on-surface chemistry and characterized with scanning tunnelling microscopy and atomic force microscopy, revealing orbital densities and bond-length alternation, which show it to be doubly anti-aromatic.

  • Long polyynes have fascinating properties but they are difficult to synthesize as a consequence of their high reactivity. Now, it has been shown that cobalt carbonyl complexes can be used as masked alkyne equivalents, enabling the preparation of stable polyyne polyrotaxanes with up to 34 contiguous triple bonds.

  • Synthetic oligo-/polyynes with unprecedented length are used to model the elusive carbon allotrope carbyne. Spectroscopic and physical analyses show that endgroups influence the properties of shorter derivatives, but these effects predictably diminish in longer molecules. Molecular symmetry documents the evolution of characteristics from oligoynes to polyynes and offers predictions for the D∞h structure of carbyne.
