New Anthraquinone Dyes with Different Side Group Positions for LCD Color Filters
Quinoline group was substituted in 1,4-position, 1,5-position, and 1,8-position of anthraquinone to synthesize three new chemical compounds for color filters. A systematic study was conducted on changes in physical properties of the synthesized compounds in the substituted positions in terms of optical properties and thermal properties. The extinction coefficient (E) was extremely high, which was more than 4.22 in log scale for the synthesized compounds, and the value of T-d was higher than 300 degrees C. Both optical properties and thermal stability are qualified as commercial compounds.
