Year: 2026

Type: article

Abstract: ABSTRACT We report the synthesis of a new class of main-chain polysulfate photosensitizers featuring aggregation-induced emission (AIE) activity. These polymers were prepared through Sulfur(VI) Fluoride Exchange (SuFEx) click polymerization between a bisfluorosulfate-functionalized AIE monomer and various phenolic derivatives. The resulting networks combine excellent thermal stability with strong solid-state fluorescence and extended π-conjugation, enabling efficient absorption of visible light and robust photophysical performance. Under photoirradiation, the polysulfates generate singlet oxygen with high efficiency, which was successfully applied to the aerobic oxidation of thioanisole under green LED illumination. Their heterogeneous polymeric nature makes them promising candidates for sustainable photocatalysis and visible-light-driven transformations.
