| Abstract: | A new receptor 3-((2-(1H-benzod]imidazol-2-yl)phenylimino)methyl)benzene-1,2-diol (1) was synthesised and developed as a highly selective fluorescent chemosensor for the detection of Hg2+ in semi-aqueous media. The fluorescence of receptor 1 was dramatically and selectively quenched on complexation with Hg2+ ion with the detection limit down to 0.20 μM. The developed sensor was successfully applied for the determination of Hg2+ content in water samples. Density Functional Theory (DFT) calculations were performed to study the mechanistic behaviour behind the binding of Hg2+ with receptor 1. |
