| 中文摘要: |
| 以氯桥二聚体[Ir(dfppy)2(μ-Cl2)]2、1-苯基-1,3-丁二酮为原料合成了一种铱磷光配合物Ir(dfppy)2(phbudio)，产率86.0%，并通过元素分析、核磁共振谱、质谱和红外光谱表征确认了目标产物的化学结构。通过紫外-可见吸收以及荧光光谱对其光物理性质进行测试，其常温最大发射位于522 nm处，显示发射强烈的绿光，初步推测该铱磷光配合物发射可能来自金属铱到环金属配体和辅助配体的电荷转移(MLCT)跃迁。 |
| 英文摘要: |
| Iridium phosphorescent complex Ir(dfppy)2(phbudio) was synthesized from chloro-bridge dimer [Ir(dfppy)2(μ-Cl2)]2 and 1-phenyl-1,3-budione, with a yield of 86.0%. The chemical structure of the target product was confirmed by elemental analysis, NMR (1H), FT-IR and MS. The maximum emission at room temperature was 522 nm, showing strong green light. It was speculated that the iridium phosphorescence complex emission may be from the charge transfer (MLCT) transition from metallic iridium to ring metal ligands and auxiliary ligands. |
