A novel visible-light sensitive dye-onium salt photoinitiator 新型感可见光的染料鎓盐光引发体系
In the arylamine/ onium salt ( DPIOC) systems, it could be observed that rate of electron transfer increases with the decrease of oxidation potential of the arylamines, i.e., TMPD> DMA> TPA> DPA. 在不同芳胺/碘鎓盐(DPIOC)组成的体系中,可观察到电子转移速度随芳胺的氧化还原电位下降而增加:TMPD>N,N-二甲基苯胺>三苯胺>二苯胺。
Comparing the quenching constants obtained by intensity measurement with that obtained by lifetime measurement, it is confirmed that the quenching is dynamic process and no charge transfer complex is formed in ground state between the fluorophore and the onium salt. 比较荧光强度和荧光寿命测定得到的猝灭常数,表明猝灭是动态过程,敏化剂与鎓盐间没有基态复合物生成。

By taking into account the generally accepted photolytic mechanism of onium salt and the possible involvement of solvent and monomer in the initiation, the kinetics of solution polymerization was interpreted. 根据普遍接受的硫鎓盐光解机理并假设溶剂和单体均可不同程度地参与引发反应,解释了溶液聚合中单体影响的动力学规律。
