“…These radicals were capable of regenerating a lower oxidation state activator from a higher oxidation state deactivator ( Figure 5). [49] Many UV and visible light sensitive compounds including unimolecular [50][51][52][53] and bimolecular free radical photoinitiators, [50,54] dyes, [52] semiconducting nanoparticles [55][56][57][58][59][60] and metal carbonyls [61] were used to photochemically initiate and control the ATRP process ( Table 2).…”

“…In a recent study, the visible light-induced ATRP was successfully mediated by benzyl alcohol grafted niobium(V) chloride (NbCl 5 ) nanoparticles as a heterogeneous photocatalyst with ethyl 2-bromoisobutyrate as initiator led to the well-defined polymers with predicted molecular weights and narrow molecular weight distributions (M w /M n =1.16~1.30). [59] The niobium complex nanoparticles could be reused as photocatalysts in five further cycles without significant loss of control or activity.…”

Photomediated controlled radical polymerization is a versatile method to prepare, under mild conditions, various well-defined polymers with complex architecture, such block and graft copolymers, sequence-controlled polymers, or hybrid materials via surface-initiated polymerization. It also provides opportunity to manipulate the reaction through spatiotemporal control. This review presents a comprehensive account of the fundamentals and applications of various Photomediated CRP techniques, including atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT), nitroxide mediated polymerization (NMP) and other procedures. In addition, mechanistic aspects of other photomediated methods are discussed.

“…To expand these approaches to particular applications where the reactions need to be conducted at low temperatures (e.g., polymerization of monomers with low ceiling temperatures or biochemical applications), a photoinduced radical polymerization process becomes an excellent candidate . Many works have recently been reported in this field such as photo‐ATRP 69, or photo‐RAFT . The CuCs‐based PISs proposed so far are capable of initiating photo‐ATRP.…”

International audienceThe utilization of visible lights for the fabrication of polymeric materials is recognized as a promising and environmentally friendly approach. This process relies on the photochemical generation of reactive species (e.g., radicals, radical cations, or cations) from well-designed photoinitiators (PIs) or photoinitiating systems (PISs) to initiate the polymerization reactions of different monomers (acrylates, methacrylates, epoxides, and vinyl ethers). In spite of the fact that metal complexes such as ruthenium- or iridium-based complexes have found applications in organic and polymer synthesis, the search of other low-cost metal-based complexes as PISs is emerging and attracting increasing attentions. Particularly, the concept of the photoredox catalysis has appeared recently as a unique tool for polymer synthesis upon soft conditions (use of light emitting diodes and household lamp). This highlight focuses on recently designed copper and iron complexes as PI catalysts in the application of photoinduced polymerizations (radical, cationic, interpenetrated polymer networks, and thiol-ene) or controlled radical polymerization under visible light irradiatio

“…In addition to iridium, transition‐metal complexes such as ruthenium, iron, niobium, dinuclear gold, and zinc‐based/zirconium/indium metal–organic frameworks have been used as photocatalysts for light‐mediated polymerization. A recent study by Matyjaszewski and co‐workers sought to provide a direct and simplified iron‐mediated photoATRP approach for polymerization of methacrylates without the need for additional ligands, reducing agents, and radical initiators.…”

“…Further studies by directly attaching trithiocarbonates to TPP to create electron donor–acceptor system revealed that efficiency of trithiocarbonates activation can be increased, and therefore, allowing for a higher rate of acrylate polymerization. [57,98c] On the other hand, ZnTPP was able to successfully activate different trithiocarbonates (BTPA, CDTPA, and DDMAT) to enable polymerization of MA while a sluggish polymerization was seen with MMA due to poor activation of dithiobenzoate (CPADB and CDB). The selective activation of trithiocarbonates by ZnTPP was then exploited to mediate polymerization of different (meth)acrylates, (meth)acrylamides, styrenics, and photocleavable monomers .…”

to fold into secondary, tertiary, and quaternary structures with respect to their functions in the cell. [1] Regulation of protein synthesis by ribosomes is carried out with precise spatial, temporal and sequence control that is provided through protein-protein and protein-RNA interactions. Mimicking cellular regulation in terms of spatial, temporal, and sequence control for the synthesis of synthetic polymers is an arduous task in polymer chemistry. However, the implication of this technology is indisputable considering that the current billion-dollar polymer industry is geared toward engineering materials such as coatings, [2] thermosets, [3] foams, [4] dental adhesives, [5] microelectronics, [6] laser direct imaging, [7] stereolithography for 3D printing, [8] and holographic recording, [9] based on irreversible temporal control of initiation.
