A coordination polymer (CP) based on Co(II), {[Co(Ox)(H2O)3] · 2H2O}n (KA@CP2_ARS), has been synthesized using 1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene (Timb) and potassium oxonate (OxK) at room temperature which was examined by single-crystal X-ray diffraction. KA@CP2_ARS contains a one-dimensional (1-D) helical chain that is extended through hydrogen-bonding interactions to form two-dimensional (2-D) and three-dimensional (3-D) supramolecular networks. KA@CP2_ARS demonstrates highly selective luminescent performance for IPA, Co2+, MnO4–, and uric acid with detection limits of 0.214, 0.16, 0.076, and 0.65 ppm, respectively, among the screened analytes. KA@CP2_ARS displays strong photocatalytic activities for degrading 88.6% of methyl violet dye under ultraviolet irradiation. [ABSTRACT FROM AUTHOR]

A Zn(II)-based polyrotaxane 1D coordination polymer, {[Zn(Or)(Bimb)(H2O)]2·2H2O}n, 1 (Or = orotate; Bimb = 1,4-bis[(1H-imidazol-1-yl)methyl]benzene), has been synthesized. 1 provides for luminescent sensing of acetone, Fe3+, MnO4–, nitrofurantoin (NFT), uric acid (UA), and sucrose. The coordination polymer displays exceptional intensity quenching of ∼96.1% with 200 mg/dl of sucrose in aqueous solution. In addition, the reactivity of 1 to photocatalytically degrade the organic dye methylene blue (MB), a hazardous organic pigment, was established. 1 was able to degrade the dye due to the generation of reactive oxygen species.

• MOF-based selective sensor for detection of environmental contaminants. • A new MOF [Co(Cei)]nis synthesized with the ligand Bis(2-Carboxyethyl)isocyanurate at room temperaturewith face-centered cubic (fcu) topology. • [Co(Cei)]ncan effectively detect trichloroacetic acid (TCA) in model and real human urine samples showing detecting concentrations as low as 1.09 ppm in real human urine. • MOF-based photocatalyst for degradation of dyes without producing secondary pollution. • Future challenges, opportunities and perspectives discussed. The Co(II) ion was combined with the ligand Bis(2-Carboxyethyl)isocyanurate at room temperature to form a new MOF, [Co(Cei)] n. This polymer was then characterised using various techniques including FT-IR analysis, Powder X-ray diffraction, thermal analysis, and SEM-EDAX analysis. Single crystal X-ray analysis reveals that the compound [Co(Cei)] n forms a 12-c connected uninodal net with a point symbol of {324.436.56}. This net has an underlying net with face-centred cubic ( fcu ) topology, which can effectively detect TCA in human urine. Furthermore, it demonstrates exceptional specificity by detecting concentrations as low as 1.09 ppm in real human urine. Extensive study has been conducted on the recyclability and photocatalytic effectiveness of [Co(Cei)] n for the degradation of organic dyes. Out of the 13 dyes studied, the photocatalytic breakdown efficiency of [Co(Cei)] n is highest for the potentially dangerous organic dyes Neutral Red (NR), with highest percentages of degradation i.e. 93.44 %.
