研究了光产酸剂对 γ 射线的敏感性：N-磺酰氧基邻苯二甲酰亚胺 2、N-磺酰氧基琥珀酰亚胺 3、N-磺酰氧基 1、8-萘二甲酰亚胺 4、N-甲苯磺酰氧基 5-降冰片烯-2、3-二甲酰亚胺 5、三苯基锍三氟甲磺酸 6、二苯基氯化鎓 7 和氯仿 8. 通过使用酸敏感染料荧烷染料 1a 来监测产酸效率。 γ辐照效率按7>2>6>5>3>4的顺序降低。在8的情况下，伴随着1a的分解。 7和8由于产生挥发性氯化氢而没有实际用途。其他(2-6)产生甲磺酸、对甲苯磺酸或三氟甲磺酸，这些酸不像氯化氢那么容易挥发。 N-磺酰氧基酰亚胺化合物(2-5)在实际用作剂量计方面具有优势，因为这些试剂溶解在极性或非极性溶剂中。
The sensitivities to γ rays were investigated for photo acid generators: N-sulfonyloxy phthalimide 2, N-sulfonyloxy succinimide 3, N-sulfonyloxy 1, 8-naphthalimide 4, N-tosyloxy 5-norbomene-2, 3-dicarboximide 5, triphenylsulfonium trifluoromethane-sulfonate 6, diphenyliodonium chloride 7 and chloroform 8. The acid generation efficiency was monitored by the use of acid sensitive dye, fluoran dye 1a. The efficiency for γ irradiation decreased in the order 7>2>6>5>3>4. In the case of 8, decomposition of 1a was accompanied. 7 and 8 were of no practical use because volatile hydrogen chloride was generated. The others (2-6) generate methanesulfonic acid, p-toluenesulfonic acid or trifluoromethanesulfonic acid which are not so volatile acid as hydrogen chloride. N-sulfonyloxy imide compounds (2-5) have an advantage for practical use as dosimeter because these reagents dissolve in either polar or nonpolar solvent.
