Description

(Perfluoro-n-Octyl)Phenyliodonium Trifluoromethanesulfonate is a highly fluorinated diaryliodonium salt, a specialized class of photoacid generators (PAGs) and fluorinated synthons. This compound matters for its exceptional ability to generate strong superacids upon photolysis or thermal activation, making it a critical performance additive in advanced material formulations. It is primarily needed by manufacturers in the electronics, photoresist, and specialty polymer industries for high-resolution patterning and surface modification.

Application

• Photoacid Generator (PAG) for Advanced Photoresists: A key component in chemically amplified resists (CARs) for deep-UV (DUV), extreme-UV (EUV), and electron-beam lithography in semiconductor manufacturing.
• Cationic Photoinitiator for Polymerization: Initiates the cross-linking and polymerization of epoxy, vinyl ether, and other cationically curable monomers under UV light for coatings, adhesives, and inks.
• Surface Functionalization Agent: Used to introduce highly fluorinated phenyl groups onto material surfaces, imparting oleophobic, hydrophobic, and low surface energy properties.
• Fluorinated Building Block in Organic Synthesis: Serves as an efficient arylating or perfluoroalkylating agent in the synthesis of complex fluorinated molecules for pharmaceuticals and agrochemicals.
• Catalyst/Co-catalyst in Fluorination Reactions: Facilitates specific fluorination and trifluoromethylation reactions in fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition and moisture uptake. Keep away from strong bases and incompatible materials.
