Sautrot-Ba, P; Bogliotti, N; Brosseau, A; Bourgon, J; Mazeran, P-E; Lalevee, J; Morlet-Savary, F; Versace, D-L, Macromolecular Materials and Engineering, 2018, 303, 1800101.

Unusual photochemical properties of an Ag(I)‐derived complex, i.e., bis[(µ‐chloro)bis(triphenylphosphine)silver (I)] ([Ag](PPh3)) are demonstrated when used in free‐radical photopolymerization reactions: i) [Ag](PPh3) can act as an innovative photoinitiating system when associated with a commercial type I photoinitiator 2,2‐dimethoxy‐2‐phenylacetophenone to overcome the oxygen inhibition effect during the free‐radical photopolymerization of acrylate monomers, thus accelerating the kinetics of polymerization under air; ii) silver‐based nanoparticles can be in situ generated under air, thus leading to new antibacterial coatings which prevent the growth of Escherichia coli and Staphylococcus aureus after few hours of incubation.
