Abstract
Abstract Tricarboxylic acid 3,5-bis(-carboxy-phenoxy) benzoic acid (H3BCPBA) 1,5-bis(imidazol-l-yl)-benzene(bib) ligands and cadmium nitrate were used to synthesize two new metal–organic frameworks with different structure under the hydrothermal and solvent thermal conditions, namely [Cd(HBCPBA)(bip)]n (1) and [Cd2(HBCPBA)2(bip)0.5]n (2). We determined the structure of two metal-organic frameworks by XRD, and characterized their structures by TG and powder X-ray diffraction (PXRD). Also we tested the fluorescence properties of the two coordination polymers at room temperature. The results showed the Complex 1 crystallizes in the Hexagonal space group P65, with tentacle structure. Complex 2 crystallizes in the Monoclinic space group P21/c, with a layer of three interdigitated structure. Fluorescence test results show that these two complexes can be used as fluorescent probes to selectively detect and identify Fe3+ ions in water.
