Photoinduced　atom　transfer　radical　polymerization　(ATRP)　is　an　economical　and　environment-friendly　method　for　synthesizing　polymers　with　pre-designable　structures　and　precise　molecular　weight.　Although　significant　progress　for　copper-mediated　photoinduced　ATRP　has　been　achieved,　several　drawbacks　still　remain,　such　as　poor　electron　transfer　capability　and　absorption　bands　of　photocatalysts　near　UV　region.　Herein,　imine-based　covalent　organic　framework,　TAPPy-TPA-COF,　has　been　synthesized　as　potential　heterogeneous　photocatalyst　for　photoinduced　ATRP.　The　＇living＇　feature　of　polymerizations　of　methyl　methacrylate　(MMA)　can　be　well　controlled　by　efficiency　maintain　the　balance　between　activation　and　inactivation　of　CuI　and　CuII.　The　chain　extension　experiments　have　further　demonstrated　the　chain-end　fidelity　of　polymers.　Meanwhile,　the　catalyst　recycle　experiments　have　revealed　stability　of　TAPPy-TPA-COF　toward　ATRP　processes.　These　results　support　the　feasibility　of　using　COFs　as　heterogeneous　photocatalysts　for　copper-mediated　ATRP　under　visible　light　irradiation.　©　2021　Wiley　Periodicals　LLC.
