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.
Abstract
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.
