摘要

A new luminescent metal-organic framework,{[Cd-3(HL)(2)(H2O)(3)]center dot 3H(2)O center dot 2CH(3)CN}(n) (1) (H4L = 1-(3,5-dicarboxylatobenzyl)- 3,5-pyrazole dicarboxylic acid), has been synthesized by solvothermal reaction and characterized by infrared spectroscopy, powder X-ray diffraction, thermogravimetry measurements and so on. 1 shows a new trinodal (4,4,6)-connected topology. Importantly, 1 displays intense luminescence in the solid state and high luminescent sensitivity and selectivity for Fe3+, CrO42- and Cr2O72- ions in aqueous solution, making it a potential probe for detecting these substances. The quenching mechanisms are also further discussed in detail. In addition, further research on the adsorption of dyes shows that 1 can selectively adsorb Congo red dye from other dye molecules.
