Biphenyltetracarboxylate-Based Luminescent Metal-Orgainc Framework for Sensing of 2,6-Dipicolinic Acid and Cr(VI) Oxo-Anions
Rational design of metal-organic frameworks (MOFs) as luminescent sensors, has attracted great interest in recent years. 2,6-dipicolinic acid (DPA) is the specific biomarker of Bacillus anthracis, Cr(VI) oxo-anions are toxic ions in environmental water, and the detection of DPA and Cr(VI) oxo-anions is of great significance. Herein, a new three-dimensional (3D) Cd(II) MOF, {[Cd2(bpda)(1,4-bbix)0.5(H2O)4]·H2O}n (1) (H4bpda = 2,3,3′,4′-biphenyltetracarboxylic acid, 1,4-bbix = 1,4-bis(benzimidazol-1-yl-methyl)benzene) has been synthesized and characterized. Its crystal structure is a 3D framework, which presents a trinodal (3,3,5)-connected topology with the point symbol of (42·6)(62·8)(42·62·84·102). 1 shows excellent luminescence and stability in water, which was explored as luminescent sensor for detection of DPA, CrO42- and Cr2O72- in aqueous solutions via luminescence quenching effect. The detection limits of 1 toward DPA, CrO42- and Cr2O72- are 0.90, 0.53 and 0.41 μM, respectively. Furthermore, 1 also can serve as luminescent sensor to detect DPA in serum and Cr(VI) oxo-anions in river water. The quenching mechanisms were studied by theoretical calculations, PXRD, UV-vis spectra and luminescent lifetimes. The luminescent film of 1 was prepared for the visual detection of DPA, CrO42- and Cr2O72-. This work presents an effective Cd(II) MOF as the functional platform for sensing of DPA, CrO42- and Cr2O72- in aqueous solution.
期刊介绍:
Journal of Inorganic and Organometallic Polymers and Materials [JIOP or JIOPM] is a comprehensive resource for reports on the latest theoretical and experimental research. This bimonthly journal encompasses a broad range of synthetic and natural substances which contain main group, transition, and inner transition elements. The publication includes fully peer-reviewed original papers and shorter communications, as well as topical review papers that address the synthesis, characterization, evaluation, and phenomena of inorganic and organometallic polymers, materials, and supramolecular systems.
