Zinc oxide (ZnO) was previously reported as an excellent cocatalyst for mechanically controlled atom transfer radical polymerization (mechanoATRP), but its photocatalytic properties in photoinduced ATRP (photoATRP) have been much less explored. Herein, well-defined ZnO nanocrystals were prepared via microwave-assisted synthesis and applied a heterogeneous mechano- photoATRP. Both techniques yielded polymers with outstanding control over the molecular weight, ZnO-cocatalyzed photoATRP faster than analogous mechanoATRP (conversion of 91% 1 h vs 54% 5 h). The kinetics tuned by loadings nanocrystals. PhotoATRP did not require any excess ligand versus Cu, contrast to mechanoATRP, requiring ligand, acting reducing agent. proceeded controllably without prior deoxygenation, since involved cascade reactions, leading rapid elimination oxygen. versatility robustness technique demonstrated various (meth)acrylate monomers good temporal preservation end-group functionality, illustrated formation tailored block copolymers.

Photoinduced atom transfer radical polymerization (photo-ATRP) has risen to the forefront of modern polymer chemistry as a powerful tool giving access well-defined materials with complex architecture. However, most photo-ATRP systems can only generate radicals under biocidal UV light and are oxygen-sensitive, hindering their practical use in synthesis biohybrids. Herein, inspired by photoinduced electron transfer-reversible addition-fragmentation chain (PET-RAFT) polymerization, we demonstrate dual photoredox/copper catalysis that allows open-air ATRP green irradiation.

Photoinduced reversible-deactivation radical polymerization (photo-RDRP) techniques offer exceptional control over polymerization, providing access to well-defined polymers and hybrid materials with complex architectures. However, most photo-RDRP methods rely on UV/visible light or photoredox catalysts (PCs), which require multistep synthesis. Herein, we present the first example of fully oxygen-tolerant red/NIR-light-mediated photoinduced atom transfer (photo-ATRP) in a high-throughput manner under biologically relevant conditions. The method uses commercially available methylene blue (MB+) as PC [X-CuII/TPMA]+ (TPMA = tris(2-pyridylmethyl)amine) deactivator. mechanistic study revealed that MB+ undergoes reductive quenching cycle presence TPMA ligand used excess. formed semireduced MB (MB•) sustains by regenerating [CuI/TPMA]+ activator together provides polymerization. This dual catalytic system exhibited excellent oxygen tolerance, enabling polymerizations high monomer conversions (>90%) less than 60 min at low volumes (50-250 μL) synthesis library DNA-polymer bioconjugates narrow molecular weight distributions (Đ < 1.30) an open-air 96-well plate. In addition, broad absorption spectrum allowed ATRP be triggered UV NIR irradiation (395-730 nm). opens avenues for integration orthogonal reactions. Finally, MB+/Cu catalysis showed good biocompatibility during cells, expands potential applications this method.
