| 中文摘要: |
| 以2-(4-叔丁基苯基)吡啶(p-tBu-ppy)和三水合三氯化铱为原料，在乙二醇单乙醚溶剂中反应得到氯桥二聚体，然后在碱性条件下再与p-tBu-ppy成功合成了一种铱磷光配合物三(2-(4-叔丁基苯基)吡啶)合铱[fac-Ir(p-tBu-ppy)3]。通过元素分析、核磁共振谱(1H NMR、13C NMR)、质谱、红外光谱和单晶X射线衍射等确定了分子结构。进一步采用紫外-可见吸收光谱、光致发光光谱对其光物理性质进行测试，考察不同溶剂对其光物理性能的影响。结果表明，fac-Ir(p-tBu-ppy)3常温下在二氯甲烷溶剂中最大发射位于519 nm处，显示发射绿光，可适用于有机发光二极管器件。 |
| 英文摘要: |
| A new type of iridium phosphorescent complex, tris(2-(4-tert-butylphenyl) pyridine) iridium (fac-Ir(p-tBu-ppy)3), was synthesized via the reaction of iridium trihydrate with 2-(4-tert-butylphenyl)pyridine in ethylene glycol monoethyl ether. The molecular structure was determined by elemental analysis, nuclear magnetic resonance spectroscopy (1H NMR, 13C NMR), mass spectrometry and infrared spectroscopy along with single crystal X-ray diffraction. Its photophysical properties in different solvents were investigated by using UV-Vis absorption spectroscopy and photoluminescence spectroscopy. The results demonstrate that fac-Ir(p-tBu-ppy)? exhibits a maximum emission at 519 nm in dichloromethane at room temperature, emitting green light, which suggests its potential applicability in organic light-emitting diode (OLED) devices. The solvents used in the test has no significant effect on both the maximum aborbption and emission of Ir(p-tBu-ppy)3. |
