摘      要：A new fluorescent coordination polymer(NKU-115) was constructed under solvothermal condition based on Tb^(3+)ion and H_2L(5-(4 H-1,2,4-triazol-4-yl) benzene-1,3-dicarboxylic acid) ligand, featuring high solvent and water stability. Luminescent investigations revealed that NKU-115 shows fluorescence quenching response toward Fe^(3+)in aqueous solution and the mechanism of quenching was analyzed.
