  • Indeno[1,2-b]fluorene (IF) is an extremely reactive polycyclic conjugated hydrocarbon with antiaromatic character, thus it has not been detected to date. Here, the authors present the successful generation and characterisation of IF both on-surface and in-solution.

  • The Bergman cyclization is a fascinating rearrangement reaction with implications beyond organic chemistry. It has now been shown that a reversible Bergman cyclization reaction in a single molecule sitting on an ultrathin NaCl film can be triggered and directly imaged using atomic force microscopy. The interconverted diradical and diyne products are shown to have distinct chemical and physical properties.

  • Atomic manipulation was used to control the reductive rearrangement of 1,1-dibromo alkenes to acetylenes on a NaCl surface at 5 K, and the stages of the reaction were visualized with atomic resolution using AFM. Polyynes ranging from triyne to octayne were prepared in this way, and STM was used to map their frontier orbitals and determine their transport gaps.

  • Based initially on the outcome of certain reactions but later backed up by spectroscopic evidence, chemists have proposed — for more than a century — the existence of arynes as extremely reactive intermediates in chemical transformations. Now, with the help of atomic force microscopy, it is finally possible to generate and directly visualize this elusive intermediate.

  • Atomic force microscopy (AFM) enables the imaging and manipulation of individual molecules at atomic resolution. This Review addresses experimental considerations, including operating modes and choices for tips and substrates. Examples are presented in which AFM is used to image molecules and induce bond formation or dissociation.
