高氯酸稀土邻氨基苯甲酸配合物的固相合成及Tb^(3+)的发光

Solid State Synthesis and Luminescence of Rare Earth Perchlorate with O-aminobenzoic Acid Complexes

应用固相反应法合成了稀土高氯酸盐与邻氨基苯甲酸的配合物。对配合物进行了组成分析及热谱分析,确定了配合物组成为[RE(LH)2(L)(ClO4)2]·6H2O(RE:Nd,Eu,Tb;LH:C6H4(NH2)COOH;L:C6H4(NH2)COO-)。通过IR光谱、紫外光谱及摩尔电导的测定推测了配位情况。溶解性实验表明配合物可溶于乙醇,但不溶于水。荧光光谱实验表明:固相反应合成Tb3+的高氯酸盐邻氨基苯甲酸的配合物具有良好的荧光性能。

Three coordination compounds of perchlorate rare earth(Nd^(3+),Eu^(3+),Tb^(3+)) with o-aminobenzoic acid have been synthesized by solid state reaction. The elemental analysis,molar conductivity and DTA-TG studies suggested that the complexes have the composition of ·6H_2O(RE=Nd,Eu,Tb; LH: C_6H_4(NH_2)COOH;L^-:C_6H_4(NH_2)COO^-) .IR studies indicated that the ligand L^- is bonded with RE(III) ions though two oxygen atom in carboxy group,Amino group are not coordinated .The molar conductivities indicated that ClO_4^- are coordinated with RE^(3+), coordination compounds are non-electrolyte. In the solubility experiment it was found that the complexes have hight solubility in ethanol.In the fluorescent spectra of ·6H_2O ,it was found that Tb^(3+)has a strongly luminescent property.
