A series of eco-friendly, efficient, cost-effective free radical photoinitiators has been synthesized through a one-pot esterification process, which involves acid chlorides with ester groups or benzenesulfonyl ester groups. When exposed to UV light, the product rapidly generates free radicals, demonstrating significantly improved photoinitiation performance compared to commercial BP. Photocuring tests reveal notable enhancements in product solubility and cured film properties.
