摘要:

采用新型1,3,5-三(1H-苯并[d]咪唑-2-基)苯(TBB)配体及2,5-二羟基对苯二甲酸(H2dhtp)线性配体, 以Cd(Ⅱ)离子为中心节点, 构筑了具有新型拓扑结构(unj)的手性金属-有机框架材料[Cd(TBB)(dhtp) ](配合物1). 该配合物具有较强的光致发光性能, 可分散在溶液中荧光检测硝基配合物等污染物. 其中, 4-硝基苯胺对配合物1具有高效的荧光猝灭能力, 检测限可低至0.145 mg/L, 并具有较好的选择性.

关键词: 金属-有机框架, 荧光检测, 对硝基苯胺

Abstract:

1,3,5-Tri(1H-benzo[d]imidazol-2-yl) benzene(TBB) and(2,5-dihydroxyterephthalic acid)(H2dhtp) were used as linear ligands and Cd(Ⅱ) was used as the central node to construct a new type of chiral 3D metal-organic framework materials Cd(TBB)(dhtp)(1). The strong fluorescence emission property of complex 1 and the π-π interaction of the TBB ligand made it possible to detect nitro compounds and other pollutants by fluorescence. A further study showed that 4-nitroaniline had a high quenching ability for complex 1 and the limit of detection could be as low as 0.145 mg/L, indicating that complex 1 could be used as a highly efficient and highly selective detection probe for p-nitroaniline.

Key words: Metal-organic framework, Fluorescence detection, p-Nitroaniline
