| 摘 要： | 配合物Eu(o-MBA)3phen(o-MBA:邻甲基苯甲酸酸根离子;phen:1,10-二氮杂菲)在紫外或可见光激发下,能发出很强的红色荧光.以Eu(Ⅲ)离子为光谱探针,77K下测得其高分辨激发和发射光谱.选择激发配合物的5D0能级,得到两组不同的5D0→7F2发光光谱,表明配合物中Eu(Ⅲ)离子有不同的化学环境.配合物的喇曼光谱中,羧基阴离子的反对称伸缩振动(γas(COO))和对称伸缩振动(γs(COO))谱带是明显分裂和带肩峰的宽带,说明配合物中羧基同时存在多种配位方式,这与它的晶体结构测定结果一致.

| Abstract: | The title coordination compound Eu (o-MBA)3phen (o-MBA:o-methylbenzoate, phen:1, 10-phenanthroline) fluoresces very intensely under ultraviolet or visible light.The high-resolution excitation and luminescence spectra were measured at 77 K.5D0→7F2 luminescence spectra of two different sites have been obtained by the selectively excited 5D0 levels of the complex which indicates that Eu(Ⅲ) ions in the complex have two unequally chemical environments.Bands of antisymmetric and symmetric streching vibrations in the carboxylate anion are significantly split and broad in the Raman spectrum of the complex, which show more than one coordination modes for the carboxylate group in the complex.This is in agreement with crystal structure determination of the complex. |
