Hydrogen sulfide (H2S) is a highly toxic and malodorous pollutant (with its characteristic rotten-egg odor) [[3], [4], [5]]. As a broad-spectrum toxin, H2S can damage multiple parts of the body, including the central nervous system, at concentrations higher than 100 ppm [6,7]. The...
Combining all the properties in one probe is a challenge, thus the development of fluorescent probe for H2S is an active area of the current research. Metal-organic frameworks (MOFs) composed of metal centers and organic struts have shown great potential in storage/separation, selective sensing, ...

The removal of the environmentally toxic and corrosive hydrogen sulfide (H2S) from gas streams with varying overall pressure and H2S concentration is a long-standing challenge faced by the oil and gas industries. The present work focuses on H2S capture using a relatively new type of material, ...
DNP triggers the fluorescence burst of the probe via a photo-induced electron transfer (d-PET) process excited by the electron donor. Upon reaction with H2S, the hydrogen sulfide induces CeO bond cleavage of the probe. Subsequently, the resulting phenol salts attack the a,b-unsaturated nitrile...
