  • A previous investigation of the anti-aromatic dianion of [18]annulene concluded that it consists of a mixture of two isomers. Now it has been shown that this dianion exists as a single isomer, with a different geometry from neutral [18]annulene, and that it can be reduced further to an aromatic tetraanion.

  • 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.

  • Switching the magnetic state of a polycyclic conjugated hydrocarbon in a reversible and controlled manner is challenging. Now, by means of single-molecule scanning probe microscopy, an indenofluorene isomer on ultrathin NaCl films has been shown to adopt both open- and closed-shell states. Furthermore, bidirectional switching between the two states is achieved by changing the adsorption site of the molecule.

  • Here the authors report Zn porphene, a member of a new organic metalloporphene family. Similar to graphene, these also are fully conjugated 2D polymers, but are composed of fused metalloporphyrin rings.
