Hu et al. reported that 4-chloro-7-nitrobenzo[c]-[ 1, 2, 5] oxadiazole (NBD) based R0bdG
Hu et al. reported that 4-chloro-7-nitrobenzo[c]-[ 1, 2, 5] oxadiazole (NBD) based o-phenylenediamine (OPD) group, are colorimetric gas sensing substances which can swiftly And accurately detect phosgene. [245]. however, NBD-OPD phosgene gas sensors produce HCl as by-products which could result in secondary contamination. to overcome this problem, Hu et al. reported a new ring structure material, and they introduced the synthesized sensor 1, a benzimidazole-fused rhodamine dye that can efficaciously detect phosgene gas. they have plotted the possible reaction mechanism among sensor-1 and phosgene in figure 16a. consistent with the 1H NMR spectrum of the product, the products produced after phosgene gas assay showed that it has a structure as indicated through the ring-opened N-shloroformyl -benzimadazle 2. Senor-1, with a nanofiber platform, showed color alternate and fluorescence upon exposure to phosgene gas. As shown in figure 16c, the test paper based on sensor 1 is white and green in color and fluorescent, After the reactions of the phosgene gas, the color change to darkish pink and emit pink fluorescence. [246].
