| 中文摘要: |
| 本文以2-(4-叔丁基苯基)吡啶作为环金属主配体，2,2'-联吡啶为N^N辅助配体，六氟磷酸根为抗衡离子，成功合成了一种联吡啶铱配合物(2,2'-联吡啶)双[2-(4-叔丁基苯基)吡啶]铱(Ⅲ)六氟磷酸盐( [Ir(dtbuppy)2(bpy)]PF6，dtbuppy = 2-(2,4-叔丁基苯基)吡啶，bpy = 2,2'-联吡啶)，通过多元化的表征技术验证了其化学结构。随后，利用紫外-可见光吸收光谱分析法与光致发光光谱测量技术，深入探究了其光物理特性。测试结果显示，在常温条件下，当该物质溶解于二氯甲烷中时，其最大发射波长位于573nm处，展现出鲜明的黄色光发射特性，这一特性预示着它在有机发光二极管(OLED)器件领域的潜在应用价值显著。 |
| 英文摘要: |
| In this study, utilizing 2-(4-tert-butylphenyl)pyridine as the cyclometallating primary ligand, 2,2'-bipyridine as the N^N ancillary ligand, and hexafluorophosphate as the counterion, a bipyridyl iridium complex, namely (2,2'-bipyridine)bis[2-(4-tert-butylphenyl)pyridine]iridium(III) hexafluorophosphate ([Ir(dtbuppy)2(bpy)]PF6, where dtbuppy = 2-(4-tert-butylphenyl)pyridine and bpy = 2,2'-bipyridine), was successfully synthesized. The chemical structure of this complex was rigorously confirmed through a multifaceted suite of characterization techniques. Subsequently, its photophysical properties were thoroughly investigated employing ultraviolet-visible absorption spectroscopy and photoluminescence spectroscopy. The test results indicated that, under ambient conditions and when dissolved in dichloromethane, the complex exhibited a prominent yellow light emission with a maximum emission wavelength situated at 573 nm. This distinct photoluminescent behavior underscores its significant potential for application in organic light-emitting diode (OLED) devices. |
