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 ...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）-l,3,5-triazine（TZ1）, 2-[2-（3,4-dimethoxyphenyl）ethenyl]-4,6-bis（trichloromethyl）-1,3,5-triazine（TZ2） and 2-（1,3-benzodioxol-5-yl）-4,6-bis（trichloromethyl）-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.展开更多

The acrylic thin film modified with methoxysilane containing PAG was formed on a glass substrate and irradiated with ultraviolet rays to promote sol-gel reaction by catalytic action of acid which was generated from PAG. And then the film was hardened with microwave irradiation, yielding organic-inorganic hybrid polymer film having hardness, highly transparency and strong adhesion with a glass substrate. Since this reaction only occurred in the optically (UV) irradiated regions, by exploiting the difference between the adhesivenesses of these regions photo-irradiated through photomask with a glass substrate, it was possible to form a patterned film with pitch of 100 to 50 μm by a simple lift-off method. A pigment-containing film using latent pigments (with subtractive three primary colors of coloring materials) and a patterned film were prepared, and it was possible to make these films multi-colored by varying the mixing ratio of the pigments. This multi-colored film-preparation method is effective for simply and efficiently forming a color-filter film by applying optical and microwave irradiation.展开更多
