【摘要】 利用镉金属络合物离子和芳香有机二羧酸配体与铀酰离子在水热条件下反应,合成了d-5f异金属有机配位聚合物,通过X-射线单晶衍射方法确定其晶体结构,并对其红外、紫外-可见和荧光光谱进行了经验归属。晶体结构解析表明:化合物为蜂窝状主-客体型结构的化合物,其中主体框架为蜂窝平面的网络结构,客体是八面体构型的金属络合物,紫外-可见光谱表明此化合物具有半导体性质,荧光光谱表明此化合物具有典型的铀酰离子发射峰。这些实验结果可为新型d-5f异金属有机配位聚合物的设计合成与应用提供有价值的理论与实验依据。更多还原

【Abstract】 Based on the reaction of Cadmium metallic complexes ions, aromatic organic dicarboxylic acid and uranyl ions under hydrothermal conditions, heterometallic organic coordination polymers was obtained and its crystal structure was determined by X-ray single crystal diffraction method. The empirical assignments of infrared, ultraviolet-visible and fluorescence spectra of these coordination polymers were given. Crystal structure analysis shows that it is host-guest type structure of the compound; the main framework is honeycomb-like flat network structure; the object is octahedral configuration of metal complexes; Uv-vis spectra shows that the compound has semiconductor properties; fluorescence spectrum indicates that this compound has a typical emission peak of uranyl ion. The results of these experiments will provide valuable theoretical and experimental basis for the synthesis and application of new d-5f heterometallic-organic coordination polymers.更多还原
