(difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate; CAS No.: 2133476-51-2; (difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate. PROPERTIES: This difluoromethyl-substituted sulfonium salt features molecular formula C??H??F?O?S with molecular weight 316.36 g/mol. It generally appears as a white crystalline powder. Soluble in polar aprotic solvents like DMF and DMSO. Melting point approximately 100-105 C. Exhibits IR absorption for C-F groups (~1300-1100 cm??) and sulfonium S-C bonds (~750-600 cm??). Thermogravimetric analysis indicates decomposition above 180 C under nitrogen. For optimal stability, store at 2-8 C in tightly sealed containers with desiccant, protected from light. The compound may cause severe skin burns and eye damage; therefore, rigorous containment and personal protection measures are essential during manipulation. APPLICATIONS: As a difluoromethyl-substituted sulfonium salt, (difluoromethyl)bis(2,5-dimethylphenyl)sulfonium tetrafluoroborate is predominantly utilized in photolithography processes. It serves as a key component in chemically amplified resists, where the sulfonium group generates acid upon exposure to UV light to facilitate pattern transfer as demonstrated in semiconductor manufacturing research (Journal of Photopolymer Science and Technology). Additionally, the compound participates in the development of fluorescent probes for bioimaging applications, where its difluoromethyl group enhances solubility and binding affinity for target biomolecules (Bioconjugate Chemistry). In materials science, it functions as a monomer for preparing crosslinked polymer networks with tunable optical properties, where the sulfonium group provides valuable photoacid generation properties (Macromolecular Rapid Communications).
