Outline of Final Research Achievements

Nanocarbons are a group of materials with unique mechanical and electronic properties that have been widely studied and applied. In recent years, the development of bottom-up synthesis methodologies from small organic molecules has been pursued to achieve precise synthesis of nanocarbons. However, nanocarbons aggregate easily in many solvents, and bottom-up synthesis requires the introduction of many modifying groups such as alkyl groups. Since modification groups can change the physical properties of nanocarbons, it is desirable to develop a method for synthesizing unmodified nanocarbons. In this study, we applied the concept of solid-phase synthesis to the precise synthesis of unmodified polyarylenes and established the methodology. We also developed a technique for transferring unmodified polyarylenes to other materials.
