For the selective colorimetric detection of Co(II) ions, an Azo-Quinoline probe-based imprinted gel sensor has been developed. Colorimetric studies show a prominent visual response to Co(II) ions, allowing detection of these ion by using imprinted gels. A reversible study confirmed that the quinoline probe can be used as a secondary sensor for anions by changing the color of the gel from red to orange. This gel also showed a reversibility system in the presence of EDTA. When Co(II) ions are added to the imprinted gel, the color of the solution changed from orange to red due to the formation of a Co(II)/(E)-2-((4-((8-hydroxyquinolin-5-yl)diazinyl)phenyl)methyl)amino)ethyl acrylate complex, which induced intramolecular charge transfer (ICT) processes. |
