Atom transfer radical polymerization (ATRP) has been in the spotlight by far as a groundbreaking synthetic method, combining the strong points of living polymerization with those of radical polymerization. However, contamination of the polymer by the metal catalyst remains a challenge, which limit the use of the traditional ATRP method in electronic or biomedical applications. These drawbacks have spawned investigations into the development of organic catalysts for photo-controlled, metal-free polymerizations. In this talk, I will discuss the metal-free ATRP process mediated by light and catalyzed by an organic-based photoredox catalyst. The influences of different monomers, initiators, and solvents were examined, and the diverse copolymer structures including block copolymers, cross-linked copolymers, and amphiphilic diblock copolymers were realized. |
