| Abstract: | A new fluorescent coordination polymer (NKU-115) was constructed under solvothermal condition based on Tb3+ ion and H2L (5-(4H-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 Fe3+ in aqueous solution and the mechanism of quenching was analyzed. |
