| Abstract: A novel coordination polymer (CP) {[Cd2(L)(1,4-bimb)1.5(DMF)2]·DMF}n (1) (H4L=5,5′-[1,1′-biphenyl-4,4′-diylbis(oxy)]diisophthalic acid, 1,4-bimb=1,4-bis(imidazole-1-ylmethyl)-benzene) has been designed and synthesized through solvothermal reaction. Structural analysis shows that Cd(Ⅱ) is connected by H4L and 1,4-bimb to form a 2D network, and 1,4-bimb further expands the 2D network into a 3D framework. CP 1 can be used as an excellent fluorescence sensor for Fe3+ and 4 -nitrophenol (4 -NP), with low detection limits and good anti-interference. The detection limits of Fe3+ and 4-NP were 0.034 and 0.031 μmol·L-1, respectively. In addition, the fluorescence quenching mechanism was studied. 1 was successfully applied to determine Fe3+ and 4-NP content in the Yanhe River water sample. |
