Three new chromogenic receptors have been synthesized with the primary objective of facilitating the selective recognition of PO43−and CO32− ions in an organo‐aqueous medium. R1 and R2 exhibit an extraordinary detection limit aligning with both EPA and WHO guidelines. R1 shows LOD of 0.135 ppm for PO43− and 0.175 ppm for CO32−, while R2 sets forth a LOD of 0.427 ppm for PO43− and 0.729 ppm for CO32−. The binding mechanism involves intramolecular charge transfer (ICT) band are substantiated by comprehensive studies that include UV‐Vis titration, 1H‐NMR titration, DFT studies and electrochemical studies. Chemosensors were employed in the formulation of logic gate, the fabrication of a paper strip test kit and its application in RGB color sensor device.

Three chemosensors ISA‐1, ISA‐2, and ISA‐3 were synthesized for the detection of Cu2+ and Hg2+ ions in a 50% H₂O‐DMF solution. ISA‐1 is specifically designed for the detection of Cu2+ ions, while ISA‐2 can detect both Cu2⁺ and Hg2⁺ ions. Upon interaction with Cu2⁺, ISA‐1 undergoes a naked‐eye colorimetric transition from pink to blue. ISA‐2 exhibits a similar pink‐to‐blue color change in the presence of Cu2+ ion, however, colorless when exposed to Hg2+ ion. The detection limits for Cu2+ using ISA‐1 and ISA‐2 are 0.574 ppm and 0.0074 ppm, respectively, both of which are significantly lower than the WHO guideline of ≤1.5 ppm for Cu2+ in drinking water. These chemosensors have also been successfully integrated into paper strips and logic gate systems and applied for the analysis of water and food samples.
