These receptors, Sn1 and Sn2, exhibit selective colorimetric and fluorogenic responses towards fluoride (F\n                    <jats:sup>\u2212<\/jats:sup>\n                    ) and cyanide (CN\n                    <jats:sup>\u2212<\/jats:sup>\n                    ) anions. The addition of these analytes significantly enhances the fluorescence intensity. Sn1 exhibits a limit of detection (LOD) of 1.65\u2009\u03bcM for F\n                    <jats:sup>\u2212<\/jats:sup>\n                    and 1.7\u2009\u03bcM for CN\n                    <jats:sup>\u2212<\/jats:sup>\n                    ions, while Sn2 has an LOD of 4.8\u2009\u03bcM for F\n                    <jats:sup>\u2212<\/jats:sup>\n                    detection using the fluorometric method.

The larger binding constant and lower LOD of Sn1 and Sn2 demonstrated the ability to sense even traces of target analytes. The sensing ability of Sn1 and Sn2 was comprehensively evaluated through optical, electrochemical, and theoretical studies. The Benesi\u2013Hildebrand and Job's plots suggested a 1:1 binding interaction between the Sn1\/Sn2 and respective anions. The ESI mass spectra of Sn receptor + anion complexes revealed that the sensing mechanism involved the exchange of an axial Cl atom with the incoming anions. In addition to that, real\u2010time analysis was also carried out for the detection of F\n                    <jats:sup>\u2212<\/jats:sup>\n                    ion present in the toothpaste and RGB
