ESIPT-PET based triphenylamine-anthraquinone probe for the detection of phosgene: DFT studies, real-time application in soil samples and test strips

Abstract

The public's health and safety are gravely jeopardised by phosgene, a highly toxic gas. In this study, phosgene was detected by excited-state intramolecular proton transfer (ESIPT) and photoelectron transfer (PET)...

A rapid and selective “on–off” fluorescence detection of lethal pulmonary agent phosgene supplemented with theoretical approach: a cost-effective sensing tool for household bleach and soil analysis

“…Therefore, we used various soil samples to perform real-time research in order to gain a better knowledge of the release of phosgene into the soil. 35 A variety of soil samples were treated with phosgene dissolved in CH 3 CN ( c = 0.02 μM). The treated soils were allowed to dry for a while before being analysed with the probe DPBO ( c = 0.2 μM) (Fig.…”

A versatile sensor capable of ratiometric fluorescence detection of trace water and turn-on detection of Cu2+ modulating the binding interaction of a Cu(ii) complex with BSA and DNA complemented by docking studies

“…In order to apply PBA for the practical application, soil analysis has been performed by using various soil samples like clay soil, field soil and sand, detecting Cu 2+ with soil as a medium. 35 An amount of 50 mg of the soil samples was mixed with 25 mL of double-distilled deionized water. After 10 minutes of homogenization, the homogenates were filtered and centrifuged at a high speed (5000 rpm) to get rid of any leftovers.…”

Research Progress on Naphthalimide Fluorescent Probes

“…[78,79] In 2022, Liu et al synthesized a 1,8-naphthalimide-based fluorescent probe (probe 29) to detect phosgene (Figure 14). [80] Probe 29 itself with odiaminobenzene as recognition unit has no fluorescence. However, after rapid cycled reactions with phosgene, a large fluorescence intensity increase with low LOD of 0.23 nM was generated.…”
