| 제목 | Synthesis and Optical Properties of New Multi-Phenylated Carbazole Derivatives in OLED device |
| 초록 | OLEDs are currently the subject of an intense research effort due to their promise as devices for full-color large display applications. Recently, m-MTDATA, 2-TNATA and CuPc compounds acting as a HIL in OLED device, have been inserted between HTL and the transparent anode such as ITO in order to improve device performance. Unfortunately, CuPc absorbs slightly blue and red light and m-MTDATA has disadvantage of low Tg as 75C. This issues make kind of limitation to apply materials to device. In this study, we synthesized 3,6-Bis[(2,3,4,5-tetraphenyl)phenyl]-9-ethylcarbazole(BTPEC) and 3,6-Bis(7,10-diphenyl-fluoranthene)-9-ethlycarbazole(BDPEC), as multi-phenylated carbazole derivatives by using Diels-Alder reaction. Electro-optical properties of these materials were characterized by CV and, UV-visible and PL spectra. Multilayered EL devices were fabricated using these materials as HIL, HTL. |
