Fluorinated polymers are important materials that are widely used in many areas. Herein, we report the development of a metal‐free photocontrolled radical polymerization of semifluorinated (meth)acrylates with a new visible‐light‐absorbing organocatalyst. This method enabled the production of a variety of semifluorinated polymers with narrow molar‐weight distributions from semifluorinated trithiocarbonates or perfluoroalkyl iodides. The high performance of “ON/OFF” control and chain‐extension experiments further demonstrate the utility and reliability of this method. Furthermore, to streamline the preparation of semifluorinated polymers, a scalable continuous‐flow approach has been developed. Given the broad interest in fluorinated materials and photopolymerization, we expect that this method will facilitate the development of advanced materials with unique properties.
