Outline of Final Research Achievements

In this study, we have extensively studied novel pi-conjugated molecules and their assemblies synthesized by a unique catalyst-free click reaction between electron-accepting pi-conjugated molecules and amines. Concretely, we have successfully achieved the following points: (1) quantitative elucidation of the applicability of the catalyst-free click reaction, (2) development of novel functional pi-conjugated molecules and polymers by the catalyst-free click reaction between vinyl-substituted naphthalenediimides and amines, (3) development of novel organic-inorganic hybrids based on the click reaction at a solid-liquid interface, (4) elucidation of the spatiotemporal dynamics of catalyst-free click reactions using supramolecular assemblies, and (5) precise control over the supramolecular assembling process induced by the catalyst-free click reaction.
