摘　　要：We synthesized three new Ni(II) coordination polymers [Ni(LXHLPXH2O)2]- H2O(CP1),[Ni(LXNIP)]-2H2O(CP2) and [Ni(LXNDCXH20)2](CP3)[L=N,N′-bis(pyridme-3-yl)thiophene-2,5-dicarboxamide, H2HIP=5-hydroxyisophthalic acid, H2NIP=5-nitroisophthalic acid, H2NDC=2,6-naphthalenedicarboxylie acid] by hydrothermal method, which were characterized by means of infrared spectra(IR), TG analyses, PXRD and single-crystal X-ray diffraction. The CPI is a ID 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 CP-P3 were investigated. The CPI can detect Fe^3+ ions through luminescence quenching. The electrochemical properties of CPI 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^-.
