Outline of Final Research Achievements

This research aimed development of an efficient synthetic strategy for conjugated polymer materials, which serve as key materials of organic devices. C-H direct arylation reaction is a key reaction for shortcut of synthetic steps. Two steps can be omitted by using direct arylation in both monomer and polymer synthesis. Optimization of reaction conditions enables to afford high-quality materials in terms of molecular weight, structural accuracy, and purity, which are essential points for application in organic devices. The obtained polymers serve as active materials in organic light emitting diode and organic photovoltaics.
