Bistability between π-diradical open-shell and closed-shell states in indeno[1,2-a]fluorene - Nature Chemistry

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. Furthermo...
