| Outline of Final Research Achievements |
Novel molecular skeletons possessing reversible response to external stimulus have been developed for the purpose of the development of functional solid surfaces.
The novel biacridine derivatives (TBA) undergo reversible electron transfer disproportionation reaction regulated by acidification/neutralization. In addition, novel 3D π-conjugated cyclobisazaanthracenes consisting of butterfly-shaped azaanthracene derivatives (dimethylacridine, phenothiazine, and acridone) featuring a slit structure were formed via one-step cyclodimerization of dibromoazaanthracene derivatives. Furthermore, closing the slit via N-N bond formation afforded hydrazinobisanthenes, containing an embedded hydrazine structure in a fully fused bisanthene skeleton with a flexible 3D butterfly or 2D plane structure depending on the nature of the heterocycle. Hydrazinobisanthenes exhibited strong electron donor character.
