“…Furthermore, TNP is considered one of the strongest organic acids due to its composition of strong electron-withdrawing groups. In comparison to TNT, TNP exhibits higher explosive potential. − Furthermore, its widespread application in the pharmaceutical, dye, and leather sectors, as well as in the production of matches, fireworks, and rocket propellant, has inevitably resulted in soil and groundwater contamination. − The TNP has been classified as an active carcinogen by the Environmental Protection Agency (EPA), which has issued warnings regarding the detrimental health effects it can cause with protracted exposure. , The consumption of these dangerous compounds has resulted in the growth of environmental pollutants, ultimately causing soil and water contamination. − Hence, it is essential to streamline the development of a sensor probe capable of detecting heavy metal ions and explosive nitroaromatic compounds. Porous organic polymers (POPs) consist of lightweight elements, such as carbon, hydrogen, oxygen, nitrogen, and boron.…”

This research explores fluorescent covalent organic polymer (COP) as light-emitting materials due to their porous nature and π-conjugated skeleton. We successfully synthesized a fluorescent COP, named Pery-DHTP-BZ-COP, using the Sonogashira−Hagihara coupling reaction. This reaction combines 3,8-bis(4ethynylphenyl)-2, 3,4,7,8,9-hexahydrobenzo[1,2-e:4,5-e′]bis([1,3]oxazine) (DHTP-BZ) with 1,7-dibromoperylene dianhydride (Pery-Br 2 ). We confirmed the existence of the benzoxazine (BZ) ring and the overall structure of Pery-DHTP-BZ-COP using FTIR and NMR spectroscopy. The FTIR, DSC, and TGA analyses were employed to investigate the thermal ring-opening polymerization (ROP) behavior and thermal stability of Pery-DHTP-BZ-COP at various temperatures. Photoluminescence (PL) spectroscopy and ultraviolet (UV) light were used to demonstrate the fluorescence emission properties of Pery-DHTP-BZ-COP dispersed in a solution. These fluorescent properties, combined with the electron-rich nature of the COP, led us to develop a sensor for selective and accurate detection of lead ions (Pb 2+ ) and a nitroaromatic explosive, trinitrophenol (TNP). The electron-rich nature of Pery-DHTP-BZ-COP facilitates efficient electron transfer to the target analytes (Pb 2+ and TNP). This electron transfer process results in the fluorescence quenching of the COP, allowing for detection. The sensor exhibits a desirable linear response to both Pb 2+ and TNP with remarkably low detection limits of 0.5 μM (0.163 ppm) and 0.7 μM (0.16 ppm), respectively.
