一种新颖的金属有机镉配合物的合成及荧光性质研究

Synthesis and fluorescence properties of novel metal-organic Cadmium complexes

本研究运用水热法合成了结构新颖的金属有机框架物C_(28)H_(32)Cd_(3)N_(2)O_(23).通过X线单晶衍射、X线粉末衍射、TG-DTA等手段对其进行分析,结果表明该化合物属于三斜晶系空间群Pccn,a=1.8474(14)nm,b=1.2207(9)nm,c=1.6154(9)nm,热稳定性较好.此外,对其进行荧光分析,发现加入Fe^(3+),Zn^(2+),K^(+),Co^(2+)时,只有Fe^(3+)对该化合物的荧光猝灭效果最好.利用这一特性,该化合物可作为检测Fe^(3+)的荧光探针.

A novel structure of metal-organic framework C_(28)H_(32)Cd_(3)N_(2)O_(23)was synthesized by hydrothermal method and analyzed by X-ray single crystal diffraction,XRD,TG-DTA.The results showed that the crystal belonged to the triclinic space group Pccn,a=1.8474(14)nm,b=1.2207(9)nm,c=1.6154(9)nm,and had good thermal stability.In addition,fluorescence analysis of the compound showed that only Fe^(3+)had the best fluorescence quenching effect when Fe^(3+),Zn^(2+),K^(+)and Co^(2+)were added.Based on this property,the compound can be used as a fluorescent probe to detect Fe^(3+).
