摘要: 通过水热反应合成了一种Cd(Ⅱ)配合物,分子式为{(H2dbim)0.5[Cd(Hbptc)]·H2O}n (1),其中dbim=1-(4-(2,6-二甲基-2H-苯并[d]咪唑-3(3H)-酰基)甲基)苄基)-2,7-二氢-2,5-二甲基-1H-苯并[d]咪唑,H4bptc=3,3',4,4'-二苯甲酮四羧酸。配合物1为2D层状结构,点符号为{44·66}。配合物1可用于一些常见环境污染物的荧光识别。研究结果表明,配合物1能有效检测对硝基苯酚、四环素、2,6-二氯-4-硝基苯胺。计算得到对硝基苯酚、四环素和2,6-二氯-4-硝基苯胺对1的猝灭常数分别为2×102、5.4×104和2×104 L·mol-1

Abstract: A Cd(Ⅱ) complex, formulated as {(H2dbim)0.5[Cd(Hbptc)]·H2O}n (1), where dbim=1-(4-((2,6-dimethyl-2H-benzo[d]imidazol-3(3H)-yl)methyl)benzyl)-2,7-dihydro-2,5-dimethyl-1H-benzo[d]imidazole, H4bptc=3,3',4,4'-benzophenone tetracarboxylic acid, has been obtained by hydrothermal reactions and structurally characterized. Complex 1 exhibits a 2D layer with a point symbol of {44·66}. Complex 1 was used for fluorescence identification of some common environmental pollutants. The result of the research shows that complex 1 can effectively detect p-nitrophenol, tetracycline, and 2,6-dichloro-4-nitroaniline. The calculated quenching constants for p-nitrophenol, tetracycline, and 2,6-dichloro-4-nitroaniline were 2×102, 5.4×104, and 2×104 L·mol-1, respectively.
