| Abstract: | 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. |

| Keywords: | photopolymerization photosensitization onium salts charge transfer complex |
