The inherent amphiphilic property of modified p‐tert‐butylcalix[4]arene thiospirolactam rhodamine b based ligand for effective colorimetric Off‐On sensor for Hg 2+ ion in neutral aqueous condition, has been investigated by electronic spectroscopic techniques. This ligand discriminates chronic poisonous Hg 2+ ion over various alkali, alkaline earth and transition metal ions due to the presence of thiospirocyclic moiety. The ligand shows an association constant of 3.63 X 10 5 M ‐1 and a detection limit 9.65 X 10 ‐9 M for Hg 2+ ion. This ligand is also capable of penetrating into HeLa cell, which could be used to detect Hg 2+ ions in biological system using a fluorescence imaging technique.
