Abstract
In this study, two red compounds for CF pigment bearing piperidine or morpholine group at 1,5-postion of anthraquinone were newly synthesized. 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. In temperature study, 1,5-DPAQ and 1,5-DMAQ were decomposed at 184°C and 225°C.
