Abstract
AbstractA novel open‐to‐air photo RAFT polymerization of a series of acrylate and methacrylate monomers mediated by matching chain transfer agent irradiated by far‐red light in DMSO is reported. Hydroxyl radical (•OH) generated from methylene blue (MB) sensitized decomposition of H2O2 via photo‐Fenton like‐reaction is used for polymerization initiation. The “living/control” characteristic is evidenced by kinetic study, in which a pseudo first order curve and linearly increases of molecular weight with the increase of monomer conversion are observed. The living end‐group fidelity is characterized by MALDI‐TOF‐MS and 1H NMR results, and confirmed by successful chain extension. The temporary controllability is proved by light on/off switch experiment.
