An　imine-based　covalent　organic　framework,　TFPPy-Td-COF,　was　synthesized　to　mediate　photo-induced　controlled　radical　polymerization　(CRP)　with　copper　under　white　light　irradiation,　providing　polymethylacrylates　with　narrow　molecular　weight　dispersity　and　high　chain-end　fidelity.　This　new　methodology　provides　future　directions　for　CRP　using　robust　and　heterogeneous　COF-based　catalysts　under　visible　light　conditions.　This　journal　is　©　The　Royal　Society　of　Chemistry.
