Construction and application of multipurpose metal-organic frameworks -based hydrogen sulfide probe

Abstract

Abstract Hydrogen sulfide (H2S) is a toxic gas derived from the sulfur industry and trace H2S in the environment can cause serious ecological damage while inhalation can cause serious damage and lead to disease. Therefore, the real-time and accurate detection of trace sulfur ions is of great significance for environmental protection and early disease detection. Considering the shortcoming of current H2S probes in terms of stability and sensitivity, the development of novel probes is necessary. Herein, a novel metal-organic frameworks （MOF）-based material, UiO-66-NH2@BDC, was designed and prepared for the visual detection of H2S with rapid response (<6 s) and low detection limit of S2- (0.13 μM) by hydrogen bonding. Based on its good optical performance, the UiO-66-NH2@BDC probe can detect S2- in various water environments. More importantly, UiO-66-NH2@BDC probe realize imaging S2- in cells and live zebrafish.
