Abstract Photomediated Atom Transfer Radical Polymerization (photoATRP) is an activator regeneration method, which allows for the controlled synthesis of well‐defined polymers via light irradiation. Traditional photoATRP often limited by need high‐energy ultraviolet or violet light. These could negatively affect control and selectivity polymerization, promote side reactions, may not be applicable to biologically relevant systems. This drawback can circumvented introduction catalytic amount photocatalysts, absorb visible and/or NIR and, therefore, controlled, regenerative ATRP performed with dual‐catalytic cycle. Herein, a critical summary recent developments in field dual‐catalysis concerning Cu‐catalyzed provided. Contributions involved species are examined mechanistically, followed challenges future directions towards next generation advanced functional macromolecular materials.

A cooperative interfacial and ion-pairing catalysis, coupled with a molecular oxygen reduction reaction (ORR), to scale up an Atom Transfer Radical Polymerization of n-butyl acrylate (BA) from 20 mL 10 L (scale-up factor = 500) in ab initio emulsion conditions is introduced. The polymerization driven by the regeneration [CuIL]+ through CuII/Cu0 comproportionation. simultaneously converts O2 H2O2 (which then degraded sodium pyruvate) drives butyl acrylate. anionic surfactant dodecyl sulfate (SDS) facilitates catalyst transport inside outside micelles catalysis. n-Butyl polymerizations are investigated on small Cu0 wire larger powder. On scale, yielded controlled PBA-Br (Mn 32.3 × 103; Ð 1.39, ∼1.64 kg) after 9 h. Chain extension macroinitiators proved their livingness. An on-line electrochemical monitoring was also introduced determine instantaneous CuI CuII concentrations at surface during polymerization.
