Based on azo and anthraquinone moieties, new black matrix pigment materials AAQ and DAAQ were synthesized for the first time by through Suzuki C-N coupling reaction. As a result of verifying UV-visible absorption spectra of the synthesized materials, DAAQ was found to absorb the entire visible region in 400 ~ 800 nm in solution state with high extinction coefficient of 8.1 × 103 L/cmmol. Realization of black color using a single material is expected to be useful for black matrix application. Also in film state made by through spin coating, both AAQ and DAAQ absorbed the entire visible region. Synthesized materials AAQ and DAAQ respectively showed Td of 353 and 366 ℃. In case of AAQ, high thermal stability was verified with Tm measured at 267 ℃. |
