3-溴-5-(3-羧基苯基)吡啶镧配合物的合成、结构和光致发光（英文）

Synthesis,structure and photoluminescence of a lanthanum 3-bromo-5-(3-carboxyphenyl) pyridine complex

在水热条件下合成了一个新的金属-有机配合物LaL3(H_2O)2(1)[HL=3-溴-5-(3-羧基苯基)吡啶],并通过单晶X-射线衍射、元素分析、红外光谱、粉末X-射线衍射(PXRD)和热重分析(TGA)对其进行表征。单晶X-射线衍射分析揭示配合物1具有一维(1D)链结构。邻近的1D链通过氢键和π-π相互作用拓展为三维(3D)超分子结构。配合物1显示了配体L的光致发光。

One new metal-organic complex LaL3 （ H2O） 2 （1） [ HL 3-bromo-5- （ 3-carboxyphenyl ） pyridine ] been synthesized under hydrothemlal condition and characterized through single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, power X-Ray diffraction （PXRD）, and thermogravimetric analysis （TGA）. Single-crystal X-ray diffraction analysis reveals that complex 1 possesses a one-dimensional （1 D ） chain structure. The adjacent 1D chains are extended into a three-dimensional （3D） supramolecular architecture by the hydrogen bonding and π-π interactions. Complex 1 shows the photoluminescence of the L ligand.
