Synthesis of New Dye Compounds Based on Anthraquinone Moiety for Color Filter Colorants

Abstract Methoxy-pyridine group was substituted in 1,4-position, 1,5-position, and 1,8-position of anthraquinone to synthesize three new chemical compounds for color filter. Systematic study was conducted on changes in physical property of the synthesized compounds in the substituted positions in terms of optical property and thermal property. Extinction coefficient (ϵ) was extremely high above 4.03 in log scale for the synthesized compounds, and the value of Td was above 300°C. Both optical property and thermal stability were qualified as the commercial compound.
