Abstract In this work, we have synthesized and characterized a new benzimidazole appended Schiffbase‐based fluorescent chemosensor 2‐((1H‐benzo[d]imidazol‐2‐yl)thio)‐N‐(4‐(2‐(2‐(2‐hydroxy‐3‐methoxybenzylidene)hydrazinyl)phenyl)acetamide ( MBIA ) for sensitive selective detection of Hg 2+ ions. the presence ions, shows an immediate turn off response blue fluorescence color change from colorless to pale yellow in DMF‐Water (1:4 v/v) medium. forms strong complex with having binding constant 2.19 ± 0.55 × 10 7 M −1 . From results Job's plot, NMR titration, Mass spectrometric studies DFT reveal stoichiometry ‐ system is 2:1. The Limit (LOD) towards ions 2.80 −7 M. practical utility real sample analysis examined by spiking water samples collected various sources such as tap drinking water. Furthermore, its possesses significant anticancer activity against HeLa (Human cervical cancer cell line) A549 lung adenocarcinoma lines encouraging outcomes. This dual functionality sensing nature probe makes it stand alone work fields both environmental biological chemistry.
