Fluorine is the most electronegative element, and the incorporation of fluorine into organic compounds imparts properties and reactivities that are markedly different from those of non-fluorinated analogues. Owing to their unique features—such as exceptional thermal and chemical stability, water and oil repellency, non-stick behavior, low dielectric constants, and high optical transparency—organofluorine compounds, including fluorinated polymers, are widely used across a broad range of fields, from household products to industrial applications.

However, in light of issues surrounding fluorine resource availability and the environmental impact of fluorinated compounds, there is an increasing demand for the development of innovative fluorine-containing materials.

Our research focuses on the development and characterization of fluorinated polymers and organofluorine materials that combine environmental compatibility with advanced functionality. Fluoropolymers containing cyclic perfluoroalkylene structures have demonstrated enhanced water- and oil-repellency as well as improved thermal resistance, owing to their distinct intermolecular interactions compared to conventional linear perfluoroalkylene-based resins.

In addition, we have reported a variety of functional fluorinated materials, including heat-resistant and highly transparent aromatic resins derived from fluorocarbon feedstocks, strongly luminescent conjugated polymers, and electron-accepting fluorinated aromatic compounds.
