摘　　要：成功合成了两种新型锍鎓盐类光生酸剂,其结构经1HNMR和MS分析确认,并对其基本物性及在405、365nm光下乙腈溶液中的分解及产酸性能进行了研究,通过计算得出了分解及产酸量子产率.结果表明,两种化合物有较高的热分解温度和在常用有机溶剂中有较好的溶解性;在405nm光源下,4-(9′-苯基蒽基)苯基三氟甲磺酸锍鎓盐(PAGS1)和4-(4′-N,N-二乙基-1′-苯乙烯基)苯基三氟甲磺酸锍鎓盐(PAGS2)的分解量子产率分别为10%和15%,产酸量子产率为8.1%和13%;但在365nm光源下,分解及产酸量子产率均很低,说明两种光生酸剂对于405nm波长的光较敏感,适宜作为405nm光源下的光生酸剂.Two kinds of sulfonium wits as Photo-acid Generator have been successfully synthesized. Their structures were confirmed by ^1HNMR and MS. Some physical performances have also been measured. Further, their photo-decomposition and acid-forming performance in acetonitrile under irradiation at 405 and 365 nm were evaluated by the method ascertained in our laboratory. It is found that two sulfonium ,salts have high thermo-decomposition temperature and good dissolution in some organic solvents. When exposed at 405 nm, the quantum yields of decomposition of 4-（9- phenyl-anthracenyl） phenyl sulfonium salt of methyl trifluoromethanesulfonate （PAGS1） and 4-（4＇- （N, N-diethyl）- 1＇-styrenyl） phenyl sulfonium .salt of methyl trifluoromethanesulfonate （ PAGS2 ） were 10% and 15% respectively; their quantum yields of acid-forming were 8.1% and 13% respectively. However, when exposed by 365 nm, their quantum yields of decomposition and acid forming were very low. Finally, it is concluded that both PAGS1 and PAGS2 are sensitive to light at 405 nm and applicable to be used as PAG in Purple Laser CTP technology.
