Description

Diphenyliodonium Perfluoro-1-butanesulfonate is a highly reactive diaryliodonium salt, a key photoacid generator (PAG) in advanced material science. Its core value lies in generating strong superacid upon UV exposure, enabling precise cationic polymerization and cross-linking. This compound is essential for manufacturers in the electronics and high-performance polymer industries, particularly for producing photoresists, optical fiber coatings, and other UV-curable systems requiring exceptional chemical and thermal stability.

Application

• Photoacid Generator (PAG) for Advanced Photoresists: Critical component in chemically amplified resists (CARs) for semiconductor lithography, including deep-UV (DUV) and extreme-UV (EUV) processes.
• Cationic UV-Curing Initiator: Used to initiate the polymerization of epoxy, vinyl ether, and oxetane monomers in coatings, inks, and adhesives for electronics and optical fibers.
• Surface Modification & Functionalization: Enables grafting reactions and surface patterning on various substrates through photochemical decomposition.
• Synthesis of Fluorinated Compounds: Serves as an efficient electrophilic reagent or catalyst in organic synthesis for introducing perfluoroalkylsulfonate groups.
• Polymer Cross-Linking Agent: Imparts enhanced durability, chemical resistance, and thermal properties to specialty polymers upon UV activation.
• Research & Development: A valuable tool in academic and industrial R&D for developing new photopolymerizable materials and catalytic systems.

Quality Control

Our Diphenyliodonium Perfluoro-1-butanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and KF titration for moisture content, to ensure consistency and performance. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat and incompatible materials.
