Known Application

It is an iodonium salt photoacid generator (PAG) with the following uses:

- Photoacid generator (PAG)After being irradiated by ultraviolet light (UV), electron beam or laser, it releases strong acid (H⁺) to trigger subsequent chemical reactions. Mainly used in: photoresists (especially chemically amplified photoresists), microelectronics processing (such as semiconductor manufacturing), 3D lithography, micro-nanostructure patterning

- Cationic polymerization initiatorThe structure containing iodonium cations can release active cations under light to initiate polymerization reactions such as epoxy resins, vinyl ethers, etc. Used in: UV-curing coatings, photosensitive adhesives, electronic packaging materials

- Structural improvement in high-performance PAG researchCompared with other iodonium salts, the introduction of isopropyl and methyl structures can improve photosensitivity, thermal stability or solubility. The anion B(C₆F₅)₄⁻ (tetrakis(pentafluorophenyl)borate) is an ultra-weakly coordinating anion that does not undergo side reactions with the active center, which helps to improve the reaction efficiency.
