新型水性硫杂蒽酮类光引发剂的合成III

Synthesis of Water Soluble Photoinitiators of Thioxanthone Derivatives III

合成了 8个新的水性硫杂蒽酮类光引发剂 ,经红外、核磁共振、质谱和元素分析等确证了结构。同时测定了其吸收波长及荧光吸收光谱 ,计算了摩尔消光系数和荧光量子效率 ,并对其结构与光化学行为之间的关系做了初步探索。

Eight new photoinitiators of water soluble thioxanthone derivatives were prepared.These compounds were identified by IR,NMR,MS and elemental analysis.The UV absorption wavelenth, molar absorption coefficient and fluorescent quantum yield were determined.Furthermore,the relationship between structure and properties was discussed.
