Abstract:

A new environmentally friendly photo-acid generator(PAG), 1-{4'-[4,6-bis(trichloromethyl)-1,3,5-triazin- 2-yl][1,1'-biphenyl]-4-yl}-O-acetyloxime ethanone(TZ4) consisting of both an oxime ester group and a triazine group was designed and synthesized. From the measurements of absorption, fluorescence and the photo-acid generation, it was found that the novel PAG has an excellent radical-generating efficiency. And the other three bis-(trichloromethyl) triazine derivatives 2-[2-(4-methoxyphenyl)ethenyl]-4,6-bis(trichloromethyl)-1,3,5-triazine(TZ1), 2-[2-(3,4-dimeth- oxyphenyl)ethenyl]-4,6-bis(trichloromethyl)-1,3,5-triazine(TZ2) and 2-(1,3-benzodioxol-5-yl)-4,6-bis(trichlorometh-  yl)-1,3,5-triazine(TZ3) were synthesized and studied in this work. In the acid measurement, the acid-forming performance of S-triazinyl derivatives was evaluated by the method ascertained in our laboratory. The results indicate that the novel triazine has the better acid-forming performance that subsequently catalyzes the deblocking of a protecting group in copolymers.
