LCD 컬러필터용 아미노안트라퀴논 색소의 합성 및 특성 연구

Abstract

The thesis entitled "Synthesis and Characterization of Aminoanthraquinone colorant for LCD Color Filter". LCD color filter has been used colorants of dyes or pigments materials. These color materials play an important role. High purity, thermal stability, and contrast of images on the device to determine the quality of color filter materials are an important factor. Recently pigment-type color filter need to High color reproductionn, high brightness, and high contrast ratio. So, try to replace as dye-type, but dye-type color filter need to higher thermal properities. We focused on the development of anthraquinone colorants with thermal stability and solubility for LCD color filter in this research. We prepared anthraquinonesulfonamide colorants by the reaction of 1-amino-, 2-amino-, and 1,4-diaminoanthraquinone and methanesulfonyl chloride and benzenesulfonyl chloride and we has synthesised aromatic diaminoanthraquinone colorant through the reaction of 1,5- and 1,8-dichloroanthraquinone by using aniline, 2-aminobenzothiazole, and 1-aminonaphthalene. Synthesized colorants were measured by an absorption maximum (λmax) and thermal stability using a UV-VIS spectrophotometer and thermogravimetric analysis (TGA), respectively.
