biostudies-literatureUnknown16(35)Fan ZHPhotoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization is a sustainable and powerful tool to synthesize polymers and copolymers. However, the development of large-scale production and polymerizations using sunlight irradiation remain top challenges for PET-RAFT polymerizations. In this study, conjugated cross-linked phosphine (PPh<sub>3</sub>-CHCP) was explored as a heterogeneous photocatalyst for efficient PET-RAFT polymerization. This development allowed PET-RAFT processes to achieve high monomer conversions, low dispersity and good chain-end fidelity under a broad range of wavelengths and sunlight irradiation from various monomers. The heterogeneous PPh<sub>3</sub>-CHCP photocatalyst could be easily separated and reused without oChemical science16347-16354https://www.ebi.ac.uk/biostudies/studies/S-EPMC12358945biostudies-literatureSunlight-driven photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer polymerization at a large scale.PMC12358945He XYHe TXiao ZHXia LFan ZHTang LXLiu YXFang WWYu JKWang XZTang XNfalseSunlight-driven photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer polymerization at a large scale.Photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization is a sustainable and powerful tool to synthesize polymers and copolymers.
