多金属氧酸盐荧光晶态配位聚合物的合成条件研究

Study on the Synthesis Conditions of Fluorescent Crystal Coordination Polymer of Polyoxometalates

多金属氧酸盐具有结构、尺寸、组成等可调的特性,同时又具有良好的热稳定性、氧化还原能力、高质子酸性、良好的质子迁移能力及其独特的“假液相”反应场等特点。将金属与缺位多酸并引入配体相结合构筑性能结构新颖的聚合物在无机化学领域是当前有价值的研究课题。在水热合成方法下,进行了硝酸铜与缺位多酸混合物与2,6-吡啶二羧酸配位条件研究。

Polyoxometalates have the characteristics of adjustable structure,size and composition,as well as good thermal stability,oxidation-reduction ability,high proton acidity,good proton migration ability and unique“ pseudo liquid phase” reaction field.It is a valuable research topic in the field of inorganic chemistry to combine metals with absent polyacids and introduce ligands to construct polymers with novel properties and structures.In this paper,the coordination conditions of 2,6-pyridyl dicarboxylic acid and copper nitrate were studied by hydrothermal synthesis.
