Abstract: We synthesized three new Ni(Ⅱ) coordination polymers[Ni(L)(HIP)(H2O)2]·H2O(CP1),[Ni(L)(NIP)]·2H2O(CP2) and[Ni(L)(NDC)(H2O)2](CP3)[L=N,N'-bis(pyridine-3-yl)thiophene-2,5-dicarboxamide, H2HIP=5-hydroxyisophthalic acid, H2NIP=5-nitroisophthalic acid, H2NDC=2,6-naphthalenedicarboxylic acid] by hydrothermal method, which were characterized by means of infrared spectra(IR), TG analyses, PXRD and single-crystal X-ray diffraction. The CP1 is a 1D tubular structure based on[Ni-HIP]2 loops and pairs of L ligands. CP2 is a 2D 3,5-connected architecture, which consists of Ni-L linear chains and (Ni-NIP)2 double chains. CP3 is a 2D network, which features 4-connected topology. Solid-state luminescent behaviours of CP1-CP3 were investigated. The CP1 can detect Fe3+ ions through luminescence quenching. The electrochemical properties of CP1 buk-modified carbon paste electrode(CP1-CPE) has also been investigated, which has bifunctional electrocatalytic activity for oxidation of ascorbic acid and reduction of NO2-.
