The metal-free atom transfer radical polymerization (ATRP) under visible light irradiation and activated by new organic photo-catalysts (PCs) was investigated. A series of PCs based on N-trifluoromethylphenyl phenoxazine were evaluated for organocatalyzed ATRP (O-ATRP). Especially, 3,7-di(4-biphenyl) 4-trifluoromethylphenyl-10-phenoxazine enabled successful O-ATRP with good catalytic performance, producing well-defined polymers with low dispersity under irradiation with a CFL bulb, white LEDs, or sunlight. With the advantages of visible light catalysis and a metal-free strategy, these organic PCs would further broaden the scope of application of this process.
