| 中文摘要: |
| 以2-苯基吡啶(ppy)为环金属配体、4,4'-二叔丁基-2,2'-二吡啶(Dtbbpy)为N^N辅助配体，PF6-为对阴离子，合成了一种离子型磷光配合物[Ir(ppy)2(Dtbbpy)]+PF6-，产率为91.0%。通过元素分析(EA)、红外光谱(IR)、核磁共振谱(1H-NMR和13C-NMR)和质谱(MS)对其组成和化学结构进行了确认和表征。采用紫外可见光谱(UV-Vis)和光致发光光谱(PL)研究了其光物理性能，该配合物在二氯甲烷中的最大发射波长为557 nm，属于黄绿光发射离子型铱磷光配合物。 |
| 英文摘要: |
| An ionic iridium complex [Ir(ppy)2(Dtbbpy)]+PF6- was synthesized with 2-phenylpyridine (ppy) as a cyclic metal ligand, 4,4'-di-tert-butyl-2,2'-dipyridine (Dtbbpy) as an N^N auxiliary ligand and PF6- as a counter anion, and its yield was 91.0%. Its chemical structure was characterized by elemental analysis (EA), infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (1H-NMR and 13C-NMR), and mass spectrometry (MS). Its photophysical properties were studied by UV-Vis and photoluminescence spectroscopy (PL). The maximum emission wavelength of the complex in dichloromethane is 557 nm, which belongs to the yellow-green emitting ionic iridium phosphorescent complex. |
