Abstract

A novel method to enhance the singlet oxygen quantum yield of photosensitizers in aqueous solution has been developed by introducing an electron-withdrawing group into BODIPY. B-2 was prepared based on this method and shows intense light harvesting ability (ε = 6.8 × 10⁴ M⁻¹ cm⁻¹ at 643 nm) and high ¹O₂ quantum yield in aqueous solution (Φ = 0.21). B-2 has been successfully used as an ¹O₂ sensitizer for the photo-oxidation of 1,5-dihydroxynaphthalene. This method substantially improves the photooxidation capability and photostability of ¹O₂ sensitizers in aqueous solution.
