摘要
以1-苯基异喹啉,2-(4-甲基苯基)吡啶为环金属配体,三氟-1-(2-苯基)-1,3-丁二酮、三氟-1-(2-呋喃基)-1,3-丁二酮为辅助配体,合成了三种新型金属铱磷光配合物.通过核磁共振谱、质谱表征确认了 3种目标产物的化学结构,并通过紫外-可见吸收以及荧光光谱对其光物理性质进行测试,3种配合物的二氯甲烷溶液在室温下中的发射主峰分别为619、577、630 nm,在橙黄光到红光范围.实验推测,环金属配体共轭程度更高时,其发射光红移,而辅助配体中基团给电子能力越强,则发射光红移.测绘了 3种配合物的三维荧光谱图,可用作定性分析.
Abstract
Three new metallic iridium phosphor complexes were synthesized by using 1-phenylisoquinoline,2-(4-methylphenyl)pyridine as ring metal ligands,trifluoro-1-(2-phenyl)-1,3-butanedioic acid,trifluoro-1-(2-furanyl)-1,3-butanedioic acid as co-ligands.The chemical structures of the three target products were confirmed by NMR and MS characterization,and their photophysical properties were tested by UV-Vis absorption and fluorescence spectra.The main emission peaks of the three complexes in dichloromethane solution at room temperature were 619 nm,577 nm,and 630 nm,respectively,in the range of orange yellow light to red light.It was speculated that the emission light red-shifted when the ring metal ligands had higher conjugation degree,and the emission light red-shifted when the group in the co-ligands had stronger electron-donating ability.The three-dimensional fluorescence spectra of the three complexes were measured and plotted,which can be used for qualitative analysis.
