(4-FLUOROPHENYL)DIPHENYLSULFONIUM TRIFLATE Usage And Synthesis

Uses

Cationic photoinitiator. Photoacid generator.

Application

(4-Fluorophenyl)diphenylsulfonium triflate is mainly used in the chemical field as a cationic photoinitiator and photoacid generator. As a cationic photoinitiator, it decomposes under ultraviolet light to generate strong Lewis acids or Brønsted acids, thereby initiating cationic polymerization reactions.
