通过四氢噻吩和二甲硫醚与相应的溴化物或氯化物反应，然后与KSbF 6进行阴离子交换，合成了新型的六氟锑酸1-萘甲基-、肉桂基-、9-芴基四亚甲基硫鎓盐和六氟锑酸二甲基硫鎓盐。这些锍盐在低于先前报道的苄基四亚甲基锍六氟锑酸盐的温度下聚合环氧单体。它们引发自由基光聚合和阳离子聚合。加入对甲氧基苯酚、4-甲氧基-1-萘酚、2-乙基-9，10-二甲氧基蒽、N-乙基咔唑和吩噻嗪等芳香族化合物作为光敏剂，可加速光聚合反应。© 2003 Wiley Periodicals，Inc.应用聚合物科学杂志91：589-597，2004
Novel sulfonium salts, 1-naphthylmethyl-, cinnamyl-, 9-fluorenyl tetramethylene sulfonium hexafluoroantimonates, and dimethylsulfonium hexafluoroantimonates, were synthesized by the reaction of tetrahydrothiophene and dimethylsulfide with the corresponding bromides or chloride, followed by anion exchange with KSbF6. These sulfonium salts polymerized epoxy monomers at a temperature lower than previously reported for benzyltetramethylenesulfonium hexafluoroantimonate. They initiated radical photopolymerization as well as cationic polymerization. The photopolymerization was accelerated by the addition of aromatic compounds such as p-methoxyphenol, 4-methoxy-1-naphthol, 2-ethyl-9,10-dimethoxyanthracene, N-ethylcarbazole, and phenothiazine as photosensitizers. © 2003 Wiley Periodicals, Inc.
