| Abstract: A cadmium-based coordination polymer [Cd4(L)4(1,4-bib)4]·2DMA (CP1) was synthesized under solvothermal conditions, where H2L=2 hydroxyterephthalic acid, 1, 4 bib=1, 4 bis(imidazol1 ylmethyl) benzene, and DMA=N,N-dimethylacetamide. The structure was characterized by thermogravimetric analysis, elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction. The single crystal structure shows that CP1 belongs to the orthorhombic system, the space group Pna21, Cd(Ⅱ) forms a 2D plane structure through L2-, and the 2D plane structure forms a 3D network with pcu topology through 1,4-bib. CP1 shows good fluorescence sensing performance and thermal stability and realizes efficient and sensitive detection of 2,4,6-trinitrophenol (TNP), Fe3+, and fluridine (FLU). The detection limits were 0.051 μmol·L-1 (TNP), 0.65 μmol·L-1 (Fe3+), and 0.14 μmol·L-1 (FLU), respectively. In addition, the mechanism of fluorescence detection of pollutant detection was explored and a portable test paper was successfully prepared. A portable test paper could not only selectively detect FLU, but also showed different fluorescence colors in different concentrations of FLU. |
