New Emitting Materials Based on HTL Moiety with High Hole Mobility for OLEDs |
| 초록 |
New green emitting compounds based on tris(N-methylindolo)benzene, anthracene, and pyrene were synthesized for the first time. NMT-An and NMT-Py as shown in Fig. 1 were used as an emitting layer in OLED device to examine emitting property. OLED device containing NMT-An emitting layer and conventional hole transporting layer (HTL) of NPB was found to exhibit better characteristics compared to NMT-Py, with maximum EL emission at 502nm and 550nm, CIE coordinates (0.38, 0.48), and an luminance efficiency of 2.06cd/A. Also when NMT and NMT-An were used as a HTL instead of NPB with NMT-An emitter, the device showed 2.67cd/A and 2.29cd/A in luminance efficiency. NMT-An compound can be used as an emitter without separate hole transporting layer in OLED device. |
