Highly Selective, Sensitive and Reusable Colormetric Chemosensor for Naked-eye Detection of Hydrogen Sulfide under Versatile Conditions |
| 초록 |
In this presentation, we report a new colorimetic chemosensor based on Benzodipyrrolidone moiety for the detection of hydrogen sulfide (H2S). which can affect injurious defect to human body. Highly sensitive (limit of detection : 1.56uM) and selective reactivity of BDP-Br enables colorimetric response of the BDP-Br solution to the H2S by showing well-defined visible color change from yellow to colorless. We also have investigated BDP-Br does not show any differences with analytes including thiol group in UV-vis absorption so that it can be worked as high selective H2S chemosensor. Based on systemic characterizations, including UV-vis absorption and NMR spectral analyses, we revealed that BDP-Br return to precursor when it reacts with H2S. This advantageous property suggests that BDP-Br can be practically applicated for reusable chemosensor under versatile conditions. |
