The invention discloses a fluorescent probe for detecting mustard gas, a detection test paper and a preparation method. At the reaction site, add the chlorine-substituted coumarin compound and sodium hydrosulfide into the ethanol solution, stir at 0-10° C. until the chlorine-substituted coumarin is completely reacted, remove the solvent under reduced pressure, and purify the probe by column chromatography Compound 9-mercapto-2,3,6,7-tetrahydro-1H,5H,11H-pyrano[2,3-f]pyrido[3,2,1-ij]quinoline; Octylamine and polyethylene oxide are dissolved in ethanol to make a solution, the filter paper is soaked with the solution, dried and cut into strips, which is the test paper for detecting mustard gas. The probe compound of the invention has the advantages of simple synthesis, high detection sensitivity, low detection limit and high selectivity, and the prepared test paper can quickly and visually monitor the mustard gas in the gas phase, has low cost, good portability and good application prospect. |
