Metal‐Free Atom Transfer Radical Polymerization of PVDF‐Based Block Copolymers Catalyzed by Organic Photoredox Catalysts

Abstract

Front Cover: In article 2200259 by Katja Loos and Aldo Altomare, the light‐catalyzed atom transfer radical polymerization (ATRP) of PVDF‐based block copolymers with methyl methacrylate using five different organic photoredox catalysts (OPRC) is reported. The authors prove how the three OPRC operating through an oxidative quenching pathway offer a good control over the process. They also achieve successful chain‐extension and external temporal control through light ON‐light OFF process. Cover design by Dina Maniar.

Selective and Controlled Grafting from PVDF-Based Materials by Oxygen-Tolerant Green-Light-Mediated ATRP

“…Recent reports by Loos et al. explored metal-free photomediated ATRP to obtain PVDF-based block copolymers and raised importance of avoiding residual copper in these materials for biomaterials and microelectronics. , …”

“…Recent reports by Loos et al explored metal-free photomediated ATRP to obtain PVDF-based block copolymers and raised importance of avoiding residual copper in these materials for biomaterials and microelectronics. 57,58 Here, we utilize green-light-driven ATRP for grafting-from PVDF-CTFE using inexpensive eosin Y (EY) as a photocatalyst. We have recently applied it to modify NCM811 cathode binders, but without focus on synthetic conditions and its consequences.…”
