| 제목 | Synthesis and Physical Property of New Red Pigment for Color Filter Based on Anthraquinone Derivatives |
| 초록 | Maximum UV-visible absorption values of 1.5-DMAQ and 1.5-DPAQ were 488and 498nm and particularly 1.5-DMAQ showed more blue-shifted values than 1.5-DPAQ. These compounds show high molar extinction coefficient values of 103 L/mol∙cm. The synthesized materials are expected to be candidates for CF pigments. Electrochemical properties of these anthraquinone derivatives were additionally investigated by CV and HOMO levels of two compounds were 5.38 and 5.45 eV, respectively. Thermal property of the synthesized compounds, Td of 1,5-DPAQ and 1,5-DMAQ were 184 ℃ and 225 ℃. In SEM images, the surface of 1,5-DMAQ material was superior to that of the commercial red pigment, Red 254. 1,5-DMAQ could be a good candidate for red solution-processible pigment having the proper thermal property. |
