【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.更多还原
