摘要: 以二苯亚砜为起始反应物,通过改进反应溶剂,首先合成了溴化三苯基硫盐,大大缩短了反应时间,提高了该盐的反应收率.再运用银盐置换法,合成了光致酸发生剂——对甲基苯磺酸三苯基硫盐,并对其进行了红外和核磁共振表征.

Abstract: The triphenylsulfonium bromide was synthesized from the original reactant biphenyl sulfoxide with the improvement of the solvent medium. The reaction time was greatly shortened and its yield was boosted. Then the photoacid generator(PAG) triphenylsulfonium tosylate was synthesized by silver salt replacement. Its FT-IR and 1H NMR spectra were tested.

Key words: photoresist, photoacid generator, triphenylsulfonium tosylate
