新型荧光传感作用的配合物制备及性能研究

Study on the Preparation and Property of a New Fluorescent Sensor Complex

采用溶液合成法,利用过渡金属镉盐与配体L(L=1.4-二(1,2,4-三氮唑-1-甲基)苯)和5-甲基间苯二甲酸制备了一种新配合物,通过单晶衍射仪对其结构进行表征,表明该材料为二维层状结构。此外,荧光研究表明,丙酮对配合物具有很强的猝灭作用。

The title complex has been synthesized with 1,4-bis(1,2,4-triazole-1-methyl)benzene and cadmium salts under the common condition.Furthermore,we studied the compound by X-ray single crystal diffraction.The complex is triclinic crystal system with P-1 space group,the central metal cadmium(II)is seven-coordinated with pentagonal bipyramid coordination geometry.On the other hand,we have done the fluorescence properties of detection of the complex in the solvent of DMF、DMA、Methanol、Ethanol、Acetone、MeCN.The results display that the complex can be well applied in fluorescent sensor over acetone.
