| Outline of Final Research Achievements |
With atomic force microscopy, we observed adsorbate molecules at high spatial resolution and studied strain-induced on-surface reaction.
AFM with a tip functionalized by carbon monoxide successfully visualizes individual water molecules within one-dimensional water chains on a copper surface. We clarify the imaging mechanism by precise detection of the atomic force between the tip and substrate; the AFM appearance corresponds to the 'oxygen skeleton' of the water network.
Furthermore, we demonstrate azulene-to-fulvalene rearrangement of an azulene-derivative polycyclic aromatic hydrocarbon on a copper surface, which cannot be induced by conventional organic synthesis. This unique reaction is induced by the structural strain within an intermediate that has heavily distorted azulene moieties on the surface.
