摘要
二烷基(4-羟基苯基)硫鎓盐作为一类新型的光引发剂由于其合成方法简便以及具较宽的光谱范围(可延伸至300nm)。因而近年来颇受重视。由于该引发剂在光照激发后生成了共振一稳定的内鎓盐(Ylide)结构和质子酸。如下式:
In this work,the charge transfer complex formation between dialkyl-4-hydroxyphenyl su-Ifonium salt and triethyl amine in ground state has been studied.Its absorption peak was shifted to longer wave-length.Under irradiation,the photolysis of onium complex occured.The products of photolysis were analysed and compared by mass spectrography.The mechanism of the sensitized photolysis has also been discussed.
