Synthesis and Electroluminscence Properties of Organic Emitters including Electron Donor and Acceptor in a Molecule |
| 초록 |
New OLED materials such as DPAT-Ph, DPAT-Na, and DPAT-An were synthesized. Each compound has dipoles because it has a electron donor and electron acceptor in a molecule. So, they showed solvatochromism. DPAT-Ph and DPAT-Na emitted strong light in a solution state. But, while DPAT-An emitted very weak light in a solution state, it emitted strong light in a thin film state. As a result of taking an aggregation-induced emission (AIE) active test, it was identified that DPAT-An uniquely showed AIE phenomenon. DPAT-Ph showed ELmax of 469 nm in a sky-blue region. It showed 3.71 cd/A, 2.07 lm/W and E.Q.E of 3.61 %. DPAT-Na and DPAT-An exhibited ELmax of 502 and 547nm which is from yellow to yellowish green range. DPAT-Na and DPAT-An showed the high luminance efficiency of 8.09 and 17.97 cd/A and E.Q.E of 3.10 and 5.20 %. They also showed 3.74 and 8.20 lm/W. Especially, DPAT-An exhibited long device lifetime of 1380 hours. |
