摘要
通过水热合成法合成了一种新型的锌配合物[Zn_2(L_1)(L_2)_2(H_2O)_8(CO_2)_2]_n(其中L1表示三联苯-3,2’’,3’’,5,5’’,5’’’-六羧酸,L_2表示3,5-双(1-咪唑)吡啶,并通过红外光谱,元素分析和X射线单晶衍射仪进行了表征。数据分析该锌配合物通过丰富的氢键连接并构筑成二维网状结构。同时,荧光发射光谱显示合成锌配合物对Cr(Ⅵ)化合物有一定的荧光猝灭作用,使其作为新型荧光探针检测Cr(Ⅵ)污染物有重要的研究前景。
A novel zinc complex [Zn2（L1）（L2） 2（H2 O） 8（CO2） 2]n was synthesized by hydrothermal method（L1 representing terphenyl-3, 2 ＂, 5, 5＇＇, 5＇＂-hexacarboxylic acid and L2 representing 3, 5-bis（1-imidazole） pyridine）,and it was characterized by infrared spectroscopy, elemental analysis and X-ray single crystal diffractometry. The two-dimensional network structure of zinc complex was formed by connection of abundant hydrogen bonds. At the same time, the fluorescence emission spectrum showed that the zinc complex had a certain fluorescence quenching effect on the Cr（Ⅵ） compound, so it can be used as a new fluorescent probe for detection of Cr（Ⅵ） pollutants.
