| Abstract |
Atom transfer radical polymerization (ATRP) has been in the spotlight by far as a groundbreaking synthetic method. Using this process, the distribution of functional groups, molecular weight of polymers, polydispersity and others can be precisely regulated, whereby the polymers with a various structure also can be designed and manufactured. 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. The drawback has spawned investigations into the development of organic catalysts for photo-controlled, metal-free polymerizations. Herein, we investigated the metal-free ATRP process mediated by light and catalyzed by organic photoredox catalysts. The organic photocatalyst was designed by diversifying N-aryl phenoxazine. We evaluated our newly discovered organic photoredox catalysts for metal-free ATRP using a series of monomers, initiators and solvents. Also, amphiphilic block copolymer was prepared using this method to form micelles, providing a basis for the biomedical applications. |
