Sunlight-driven photoinduced electron/energy transfer-reversible addition-fragmentation chain transfer polymerization at a large scale.

ABSTRACT: Photoinduced 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 (PPh₃-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 PPh₃-CHCP photocatalyst could be easily separated and reused without o
