Three new compounds are synthesized as color filter dyes by substituting a pyridine group into 1,4-position, 1,5-position, and 1,8-position of anthraquinone core moiety. Changes in physical properties of the synthesized compounds according to the substitution position are systematically investigated in terms of optical properties and thermal properties. The extinction coefficient value (ε) of the synthesized materials is extremely high and is above 4.22 in a log scale, and Td is above 300°C with high thermal stability.
