摘　　要：以硫代水杨酸和苯硫乙酸为原料,通过两步法成功合成了一种新型的单组分硫杂蒽酮类光产碱剂。利用核磁氢谱、核磁碳谱和高分辨率质谱对光产碱的结构进行了表征,通过稳态光解及电子自旋共振波谱等对光解产物进行了系统研究。该光产碱剂在400nm附近有较强的吸收,可有效引发巯基-环氧光聚合,其引发活性优于文献报道的高效光产碱体系。A novel photobase generator （PBG） was synthesized in two steps using thiosalicylic acid and （phenylthio） acetic acid as starting materials. The structure of the PBG was characterized by ^1 HNMR, ^13 CNMR and high-resolution mass spectrometer. The photolysis mechanism was systematically studied via steady photolysis and electron spin resonance tests. The PBG showed a strong absorption at around 400 nm. Under the 365~ 500 nm irradiation, the PBG could efficiently induce thiol-epoxy photopolymerization. The initiation efficiency of the PBG was higher than that of the reported efficient PBG initiation system in the literature.
