特戊酸和含氮配体构筑的Ln(Ⅲ)配合物的结构、热稳定性和荧光性质（英文）

Lanthanide(Ⅲ) Coordiantion Complexes with Pivalates and Chelating N-Donor Ligands:Syntheses,Structures,Thermal Stabilities and Luminescence Properties

在水热条件下2个配体特戊酸(piv H)和1-H-咪唑[4,5-f][1,10]-菲咯啉(IP)和稀土金属反应得到了6个稀土配合物[Ln(piv)3(IP)2],(Ln=Nd(1),Eu(2),Gd(3),Tb(4),Dy(5),Ho(6))。结果显示,2个混合配体和不同的稀土金属形成了6个相似的零维结构,进而通过N-H…O氢键和π-π堆积作用,形成一维链状结构。6个配合物均用元素分析、粉末衍射(PXRD)、红外光谱(FTIR)进行了表征,且对配合物2和4的荧光性质及1和2的热稳定性进行了详细的分析。

A series of novel monometallic coordination complexes[Ln（piv）3（IP）2], （Ln=Nd （1）, Eu（2）, Gd（3）, Tb （4）, Dy（5）, Ho（6）, IP=1-H-imidazo[4,5-f] [1,10]-phenanthroline, pivH=pivalic acid） have been successfully synthesized under hydrothermal condition. Complexes 1~6 have been determined by single-crystal X-ray diffraction analyses, elemental analyses, IR spectroscopy and powder X-ray diffraction. The result reveals that all the six new complexes present similar 0-dimensional structures, which are further extended into the one-dimensional （1D） architectures through hydrogen bonds and π-π stacking interactions. Meanwhile, the thermogravimetric analyses of complexes 1 and 2 and photoluminescent properties of complexes 2 and 4 have also been investigated.
