摘要
A new Zn(II) coordination polymer with the formula of [Zn(L)(4,4 '-Hbpt)](n) (1, H2L = 5-[(3-carboxy-4hydroxyphenyl)sulfanyl]-2-hydroxybenzoic acid, 4,4 '-Hbpt = 1H-3,5-bis(4-pyridyl)-1,2,4-triazole) has been successfully synthesized under hydrothermal conditions. Structural characterization revealed that compound 1 displays a 2D layered structure with 4-connected sql topology. Interlayer N-H?O hydrogen bonds finally directed these 2D layers into an interdigitated 3D supramolecular framework. Interestingly, compound 1 shows moderate sensing ability for the recognition of Fe3+ ion and the minimum limit of detection (LOD) for Fe3+ is 0.05 mM, indicating that such layered structure can be applied as a luminescence probe for the detection of Fe3+ ion.
