| Outline of Final Research Achievements |
We have established efficient syntheses of a series of pi-conjugated molecules that change their aromaticity depending on external stimuli, and that, at the same time, form columnar packing structures in the solid state.
On the other hand, we also developed a chemistry of boron-doped nanographene, in which a boron atom is surrounded by polycyclic aromatic systems.
For both systems, the molecule change their conformation in the solid state due to their high molecular flexibility. The dynamic change of packing structure would be the key to switch solid-state properties of pi-electron systems in a reversible manner.
