제목 | Synthesis and Optical Properties of Novel Carbazole Derivatives Containing Coumarin Unit |
초록 | OLEDs have received much attention because of its superior advantages. In order to fabricate full-color OLED display, red, green, and blue emitters with high-efficiency, good thermal property and pure color coordinate are necessary. Especially, blue emitter requires a wide band gap compared to red, green emitters, so, it is very difficult to be well-matched with HOMO and LUMO levels of blue emitter and the other layer. Thus, development of blue emitting materials is still required. In this study, coumarin was substituted in carbazole, which shows high luminous efficiency, and 7-(3-Carbazol-9-yl-phenyl)-chromen-2-one (CP-Co), 7-(9-Phenyl-9H-carbazol-3-yl)-chromen-2-one (PHC-Co), and 7-[9-(3-Carbazol-9-yl-phenyl)-9H-carbazol-3-yl]-chromen-2-one (CPHC-Co) were synthesized. The three synthesized compounds were applied to OLED devices as emitting layers and EL performance of devices were measured. |
