On–off : A living radical polymerization procedure, which utilizes ppm levels of an iridium‐based photoredox catalyst, affords control over chain growth through mediation by visible light (see scheme; P n =polymer chain, X=halogen, M=monomer). This process can be activated and deactivated by light, enables control over the molecular weight and molecular weight distributions, and tolerates different functional groups.
