In this study, two red compounds for CF pigment bearing piperidine or morpholine group at 1,5-postion of anthraquinone were newly synthesized, and the changes of physical properties by the respective substituent of the synthesized materials were examined. It was observed that maximum values of UV-visible absorption of 1,5-DMAQ and 1,5-DPAQ were 488 and 498 nm, respectively, where 1,5-DMAQ has shown higher blue-shifted value than 1,5-DPAQ. These compounds show high molar extinction coefficient values of 103 L/molcm and can be processed in spin-coating method. The synthesized materials are expected to be candidates for CF pigments in solution process. Electrochemical properties of these anthraquinone derivatives were additionally investigated by CV and the HOMO levels of 1,5-DMAQ and 1,5-DPAQ were 5.38 and 5.45 eV, respectively. In temperature study, 1,5-DPAQ and 1,5-DMAQ were decomposed at 184 ℃ and 225 ℃. |
