Comprehensive characterization of glycopolymer brushes based on controlled light-directed grafting/detachment strategy

Herein, we present a strategy for the autonomous regulation of glycopolymer brush construction and cleavage on glass substrates using surface-initiated photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (SI-PET-RAFT) polymerization. This process involves treating...

Description
Summary:Herein, we present a strategy for the autonomous regulation of glycopolymer brush construction and cleavage on glass substrates using surface-initiated photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (SI-PET-RAFT) polymerization. This process involves treating the chain transfer agent with a photocleavable moiety and linking it to glass substrates using 3-Aminopropyl triethoxysilane (APTES). Polymerization initiates at 510 nm with ZnTPP as a photocatalyst, and the glycopolymer brushes can be detached with 305 nm light. This allows GPC and NMR characterization, demonstrating controlled polymer structures with Đ
