A naphthalimide-based fluorescence chemosensor was developed and manufactured for carbon monoxide detection. Similarly, an attempt was made to make a norbornene- based turn-on fluorescent probe for formaldehyde detection, but it failed. The advantages of fluorescent detecting systems are high sensitivity or selectivity, ease of vision, simplicity, and speedy detection. In recent decades, the usage of optical sensors has grown, and gaseous sensing fluorescence technologies have evolved dramatically, providing new methodologies and fluorophores. In project 1 (formaldehyde detection ) Iodine monochloride was added to a salicylaldehyde solution that had been produced in glacial acetic acid. After that 2-Hydroxy-5-iodobenzaldehyde , diethyl malonate, piperidine, and acetic acid were added to ethanol. The mixture was heated under reflux for 5 hours to get coumarin-based compound 3 . Further, the reaction did not proceed. In project two 5-nitro-1H,3H-naphtho[1,8-cd]pyran-1,3-dione was added with ethylenediamine and ethanol and refluxed to get 3-(2-aminoethyl)-7-nitro- 3azatricyclo[{5,13}]trideca-1(13),5,7,9,11-pentaene-2,4-dione and with that exo- norbornane anhydride was treated with acetic acid and Nap-NH2 probe was made. . We devised and synthesized a naphthalimide-based fluorescence chemosensor, Nap-NH2, and provided a new technique for CO detection in an aqueous buffer medium utilizing a fluorescence method without the need of heavy metals such as Pd, Rh, Ru, and others.
