Colorimetric Chemosensors for Hydrogen Sulfide(H2S) Detection Using Benzodipyrrolidone(BDP) Moiety-based Small Molecules. |
| 초록 |
Since reported by Bernardino Ramazzini in 1713, Hydrogen sulfide(H2S) has been identified as a one of serious volatile organic compounds. Since it can induce many harmful disorders and even death, it is important to detect the leakage of H2S gas. Here, we designed a novel colorimetric chemosensor for detecting H2S using Benzodipyrrolidone(BDP) moiety to control the reaction rate. The BDP-based chemosensor showed high selectivity and high sensitivity for H2S. We changed the BDP core part for enhancing responsivity to H2S by introducing alkyl chain and functional group. We performed UV-Vis absorption spectrum to confirm the reactivity to H2S. 1H NMR was tested to unravel the sensing mechanism. We also measured cyclic voltammetry to analyze the reduction tendency of H2S sensing. BDP chemosensor was applied to fiber, filter paper, and thin films for H2S detection, so that BDP-based chemosensor have wide potential for practical application. |
