“…It has been proved that photosensitive alkoxyamine with a chromophore could be applied to the control/living free radical polymerization according to similar observations from the unimolecular thermal alkoxyamines [22,23]. The chromophore attached to the alkylated TEMPO can act as a light absorber and then transfer the energy to the photolysis of NO−C bond via intramolecular quenching of the excited state of the chromophore [24]. We first synthesized a traditional alkoxyamine with hydroxyl group originally developed by Matyjaszewski et al [25], in which the reaction of the alkyl halide in the presence of Cu(0)/CuBr/bpy complex was used as a convenient source of alkyl radicals.…”

“…Photoinitiated polymerizations have significant advantages in medical applications and photo-specific reactions. The photoinitiated LCRPs have been applied in NMRP [17,18], ATRP [19][20][21], cobalt-mediated radical polymerization [22][23][24], organotellurium-mediated radical polymerization [25] and RAFT [26,27]. Among them, photoinitiated ATRP has been studied extensively because of the broad range of monomers and mild polymerization conditions.…”

“…Photoinitiated controlled radical polymerization methods as economic and ecological processes for the preparation of well‐defined polymers with predetermined composition, functionality, molecular structure and molecular weight at room temperature have been intensively studied . The most widely used photoinitiated controlled radical polymerization methods are adapted from thermal counterparts including iniferter methods, nitroxide‐mediated radical polymerization, atom transfer radical polymerization (ATRP), cobalt‐mediated radical polymerization, organoiodine‐mediated radical polymerization, organotellurium‐mediated radical polymerization, reversible addition–fragmentation chain transfer polymerization, etc. The earliest attempt was the direct photolysis of the terminal carbon–X bond of polymer chains.…”
