Metalorganic framework created by the association of metal ions and multitopic organic ligands are a very promising type of materials because of their broad compositional and structural diversity, low cost, and facile production. Their wide range of potential properties and applications include gas sorption, catalysis, ion exchange, sensing, drug-delivery, magnetism, fluorescence, and non-linear optics. Fluoride ions are biologically important anions because of their important role in dental care and the treatment of osteoporosis, etc. In this regard, the ability to sense uoride ions has attracted increasing attention. Herein, a new thiazoline-containing cobalt(II) coordination polymer displayed colorimetric and uorescent “turn-on” selectivity and sensitivity toward uoride anions compared to the other anions investigated through color changes from pink to blue and changes in the emission spectra at approximately 570 nm when excited at 520 nm. |
