| 제목 | New Hole Injection and Hole Transporting Materials Containing Phenothiazinly Moiety |
| 초록 | Organic light-emitting diodes (OLEDs) have been the subject of intensive investigation in the past few years because of their potential application as emissive elements for flat panel displays. Generally, multi-layered devices consisting of charge transport and emitting layers exhibit higher EL efficiency than a single-layer device. In this study, We synthesized a new HIL and HTL materials by using phenothiazinly moiety, 1,4-diphenothiazylbenzene [DPtzB], 3', 7', 3", 7"-tetrakis(N-phenyl-2-naphthylamine)-1,4-diphenothiazyl-benzene [PNA-DPtzB]. Synthesized materials exhibited high Tg in the range of 175–202 °C. These values are much better than commonly used hole transporting materials (2-TNATA and NPB). The OLED device that used DPtzB as a HIL showed the highest efficiency of 4.31 cd/A at 10 mA/cm2. |
