The color filter is an essential element for display devices, and a solvent-based wet dispersion system has been widely used for the preparation. In actual practice, dispersing additives are incorporated to prevent the aggregation and coagulation of pigment particles. Perhalgenated zinc-phthalocyanines are mainly employed for a green color filter, but they do not readily interact with dispersing agents because of large and planar structures. Thus, the use of synergists, which enhance the interaction between pigment and dispersing agents, is imperative. In this study, we present the synthesis of phthalocyanine synergists attachable to the green pigments effective for the solution dispersion. Carboxylic acid and sulfonic acid are adopted for the anchoring, which constructs the ionic and/or noncovalent interactions. The synthesized synergists are characterized by FT-IR, MALDI-TOF, 1H-NMR spectroscopy, and UV-Vis measurements. The detailed results are going to be presented in the poster. |
