【摘要】 以1,3,6-萘三磺酸钠（Na₃L）、4,4’-联吡啶（4,4’-bipy）、Tb（NO₃）₃·6H₂O为原料，通过水热合成反应制备了Tb配合物[Tb（H₂O）₈]·（L）·2（4,4’-bipy）·3H₂O（配合物1）。利用单晶X-射线衍射、傅里叶红外光谱、热重分析以及元素分析等表征手段，分析了配合物1的分子结构和组成，并且研究了其热稳定性和荧光发射性质。结果表明，Tb³⁺是八配位，呈四方反棱柱配位构型，与8个H₂O分子配位形成[Tb（H₂O）₈]³⁺;L^3-没有与金属离子配位，只平衡了分子内的正电荷；L^3-的磺酸基与配位H₂O分子之间形成氢键，将[Tb（H₂O）₈]³⁺和L^3-相连，形成一维链状结构，进而将其拓展成二维层状结构；配合物1在395、453 nm处的荧光发射峰为Na₃L的特征峰，在545、601、641 nm处的荧光发射峰为Tb³⁺的特征峰。更多还原

【Abstract】 The Tb coordination complex[Tb（H₂O）₈]·（L）·2（4,4’-bipy）·3H₂O（complex 1） was synthesized by hydrothermal reaction of sodium 1,3,6-naphthalene trisulfonate （Na₃L） and 4,4’-bipy （4,4’-bipy） with Tb（NO₃）₃·6H₂O.The molecular structure and composition of complex 1 were characterized by single crystal X-ray diffraction,FT-IR spectroscopy,thermogravimetric analysis and elemental analysis.Thermal stability and fluorescence emission properties of complex 1 were also evaluated.The results indicate that Tb³⁺is eight-coordinated in a tetragonal antiprismatic coordination configuration and coordinates with eight H₂O molecules to form[Tb（H₂O）₈]³⁺.L^3-does not coordinate with metal ion,but only balances the positive charge in the molecule.The formation of hydrogen bonds between the sulfonic acid group of the L^3-and the coordinating H₂O molecule connects the[Tb（H₂O）₈]³⁺and the L^3-to form a one-dimensional chain structure,which in turn expands into a two-dimensional lamellar structure.The fluorescence emission peaks of complex 1 at 395,453 nm are the characteristic peaks of Na₃L,and the emission peaks at 545,601,641 nm are the characteristic peaks of Tb³⁺.更多还原
