Outline of Final Research Achievements

This research aims at efficient synthesis and unique application of functional polymers that are difficult to handle due to their low solubility in organic solvents. By using our originally developed dendrimer-supported method, we were able to synthesize a variety of insoluble functional polymers such as polythiophene, poly(paraphenylene), and poly(fluorene). In addition, by hybridizing the polythiophene moiety with different materials, we have succeeded in creating novel materials with hybridized electrical conductive materials. Through these results, our research has developed into the investigation of new dendrimer structures, which has led to the synthesis of new materials such as highly water-soluble polythiophenes and polythiophenes that exhibit solubility in a wide range of solvents.
