제목 | New Hole Transporting Materials Based on Hexaarylbenzene and Aromatic Amine Moiety for OLEDs |
초록 | Three different new hole transport compounds, namely DPAP-TB, 1-PNAP-TB and 2- PNAP-TB, were synthesized by Sonogashira coupling and Diels-Alder reaction. Synthesized materials exhibited high Tg in the range of 118 to 133 oC. These values are higher than that of NPB, which is commonly used as a hole transporting material. OLED devices were fabricated by the synthesized compounds using the solution process as a hole transporting layer. Device structure was ITO/PEDOT:PSS (40 nm) /synthesized compounds or NPB (20 nm) /Alq3 (70 nm) /LiF /Al. Luminance efficiencies and external quantum efficiencies of DPAP-TB, 1- PNAP-TB and 2-PNAP-TB devices were 3.98, 4.62, 4.22 cd/A, and 1.35, 1.56, 1.43% at 20 mA/cm2, respectively. In luminance efficiency and external quantum efficiency, 1-PNAP-TB especially had superior property to NPB. |
