La section locale Midi Pyrénées de la Société Française de Physique a le plaisir d'accueillir Leo GROSS (IBM Zurich), parrain de la promotion 2019 du master 2 de physique fondamentale de l'Université Paul Sabatier, pour un séminaire SFP vendredi 12 octobre 2018 à 11h30, dans l'amphi CONCORDE de l'Université Paul Sabatier
Elusive molecules can be created using atomic manipulation with a combined atomic force/scanning tunneling microscope (AFM/STM).
Molecules that are highly reactive and short-lived under ambient conditions can be stabilized at low temperature and by using inert surfaces. Employing high-resolution AFM with functionalized tips  provides insights into the structure, geometry, aromaticity and bond orders of the molecules created and into the reactions performed .
We created radicals, diradicals , non-Kekulé molecules , antiaromatics , and polyynes  and studied their structural and electronic properties. We recently showed that the reorganization energy of a molecule on an insulator can be determined . In addition, we expanded the toolbox for the synthesis of molecules by atomic manipulation, demonstrating reversible cyclisation reactions  (see Figure) and, most recently, skeletal rearrangements .
