| Abstract: | 1,3,5-Tri(1H-benzod]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. |
