| Outline of Final Research Achievements |
Macrocyclic acenes are of interest because of the unique structure, which can be regarded as a substructure of zigzag-type carbon nanotubes. However, theoretical studies have already revealed that macrocyclic acenes are too unstable to be isolated. In this study, we focused on macrocyclic acenequinones, which could also be useful as carbon nanotube substructure.
We developed synthetic strategy to several kinds of 2,3,9,10-tetrasubstituted pentacenequinones. We found that a pentacenequinone derivative having crown ether moieties forms a macrocyclic acene structure upon binding with larger alkali metal ions (K, Rb, Cs).
