A Highly Selective and Sensitive Colorimetric Chemosensor for the Detection of Hydrogen Sulfide: A Real-time Application in Multiple platforms

Calorimetric chemosensors are found to be advantageous sensing systems due to their simplicity and favorable responsive properties. Although some colorimetric probes have been reported to detect hydrogen sulfide (H2S), the creation of rapid, highly selective and sensitive probes for the detection of H2S remains a challenging target. In this work, we established dinitrosulphonamide decorated phenanthridine and 2,4-dinitro-N-(4-(7,8,13,14-tetrahydrodibenzo[a, i]phenanthridin-5-yl)phenyl)benzenesulfonamide (PHSH), for the calorimetric detection of H2S. H2S-triggered thiolysis of PHSH resulted in a marked absorption enhancement alongside a visual color change from colorless to dark yellow. The result indicated that the chemosensor showed high sensitivity and selectivity with a fast response of less than 10?s with a detection limit as low as 6.5?nM. The chemosensor reaction mechanism with H2S was studied by UV-vis, 1H NMR, mass and HPLC analysis. In addition, the chemosensor has been used for the determination of H2S in many real-time samples.

A 2,5-diaryl-1,3,4-oxadiazole-based fluorescent probe for rapid and highly selective recognition of hydrogen sulfide with a large Stokes shift through switching on ESIPT

A new 2,5-diaryl-1,3,4-oxadiazole derived ratiometric fluorescent probe (OXDNP) for hydrogen sulfide recognition has been developed. Probe OXDNP displays highly selective and sensitive detection to HS? over other anions and thiol-containing amino acids in DMSO solution with fast response and a large Stokes shift. Through HS? induced thiolysis of the dinitrophenyl ether, the excited state intramolecular proton transfer (ESIPT) featured precursor was released, which led to dual fluorescence emission ‘turn on’ and ratiometric emission behavior of the sensing system. The pseudo-first-order reaction rate constant was calculated to be 1.234 s?1. The HS? recognition mechanism was proved by HPLC–MS and 1H NMR comparison investigations.

A fluorescence turn-on probe for hydrogen sulfide and biothiols based on PET & TICT and its imaging in HeLa cells

In this paper, a photoinduced electron transfer (PET)& twisted intramolecular charge transfer (TICT)-based fluorescent probe (1) for detecting biothiols (GSH/Cys/Hcy) and hydrogen sulfide with fluorescence turn on was developed. The probe could recognize
