Polycyclic heteroaromatic molecules are a highly useful class of organic materials. In this study, synthesis of a new azacoronene, in which both pyrrole and azulene moieties are circularly fused, was achieved in just three steps. This new azacoronene exhibited multistep reversible oxidations under electrochemical and chemical conditions. Formation of an aromatic 22π-electron conjugation and a tropylium cation (6π-electron conjugation) in the dicationic state played a key role in stabilizing this cationic species.

A new type of degradable synthetic polymer was prepared by Rh-catalyzed three-component polymerization of a bis(diazocarbonyl) compound, bis(1,3-diketone), and tetrahydrofuran. The resulting polymer, poly(β-keto enol ether), was highly sensitive to mild acidic conditions and degraded into a combination of well-defined low molecular weight compounds. With this unique degradability, the polymer could be utilized as an environmentally friendly polymeric material.

A highly conducting state has been found in a molecular crystal under UV-irradiation. The state reversibly appears in accordance with UV-irradiation, but does not appear by any other method such as raising the temperature, which often induces metallic behavior in insulating molecular crystals. The UV-excited state exhibits conduction and magnetic behavior characteristic of metallic substances. The result suggests that there is an optically accessible, but thermally inaccessible, state of matter.
