合成了1,10-邻菲罗啉-5,6-二酮,利用IR,UV,^1 H NMR,MS和元素分析确认其结构,测定了1,10-邻菲罗啉-5,6-二酮的低温磷光光谱.实验结果表明:1,10-邻菲罗啉-5,6-二酮对紫外光有较强的吸收能力,其三重态能级约为18620cm^-1,明显高于Eu^3+离子的受激发态能级,因此可预测1,10-邻菲罗啉-5,6-二酮可有效敏化Eu^3+离子的发光,有望用于制备单核或多核稀土配合物发光材料.
1,10-Phenanthroline-5,6-dione was synthesized,and characterized by IR,UV,1 H NMR,MS and elemental analysis.The low-temperature phosphorescence spectrum of 1,10-phenanthroline-5,6-dione was determined. The experimental results showed that 1,10-phenanthroline-5,6-dione had a strong ability to absorb ultraviolet light.The triplet state energy of the compound was determined to be 18620cm–1,which was much higher in energy than the resonance level of Eu3+ion.So it could be predicted that 1,10-phenanthroline-5,6-dione was able to sensitize the luminescence of Eu3+,and that this compound may be used for the preparation of mononuclear or polynuclear complexes of rare earth luminescent materials.
