Abstract
Based on the multifunctional ligand 3-(1H-1,2,4-triazol-1-yl)isophthalic acid (H(2)TIA), a three-dimensional coordination polymer, namely {[Zn(TIA)]·DMA} (n) (Zn-1) was synthesized solvothermally. Single-crystal X-ray diffraction analyses confirmed that Zn-1 is a 3D framework composed of binuclear Zn(2) paddle wheels with one-dimensional channels long the a direction. Further topological analyses revealed that MOF Zn-1 existed as a (3,6)-connected rtl binodal net {4·6(2)}(2){4(2)·6(10)·8(3)}. Furthermore, the luminescence explorations indicate that complex Zn-1 is the first MOF for luminescent probing of phthalate esters (carcinogenic organic pollutants) with a high quenching-efficiency constant and low fluorescence-detection limit.
