Synthesis of New Single Black Pigments Based on Azo and Anthraquinone Moieties for LCD Black Matrix
摘要:
Based on azo group and anthraquinone moiety, new black matrix pigment materials AAQ and DAAQ were synthesized for the first time through Suzuki C-N coupling. As a result of verifying UV-visible absorption spectra of the synthesized materials, DAAQ was found to absorb the entire visible region in 400800nm in solution state with high extinction coefficient of 8.1x103L/cm center dot mol. Realization of black color using a single material is expected to be useful for black matrix application. Also in film state made through spin coating, both AAQ and DAAQ absorbed the entire visible region.
