Cellulose-based fluorescent macromolecular sensors and their ability in 2, 4, 6-trinitrophenol detection

New Fluorescent Reporters Capable of Ultra-Sensitively Detecting Trinitrotoluene on Surfaces: A Proof-of-Concept for Finding Hidden Nitroaromatics in the Workroom

“…We have previously stated that some naphthalimides have been used for detection of trinitrophenol (TNP), an environmental contaminant and potential explosive, [52][53] therefore we wanted to study the performance of the fluorescent probe in the detection of TNP, in comparison to the detection of TNT and TNB. As in previous cases, a study of the behaviour of AR85 in the presence of excess TNP in different solvents was performed (Supp.…”

“…The obtained LODs compete favorably with those obtained in previously known examples. [52][53] Then we were curious about the possibility of detecting one explosive taggant, such as 2,4-dinitrotoluene (DNT), [70] or the most common nitrobenzene (NB). In both cases we got related titration curves and titration profiles (Supp.…”

“…Naphthalimides are known to have AIE effects, [49][50][51] and some of them have been used for detection of trinitrophenol, an environmental contaminant and potential explosive. [52][53] We selected a collection of new naphthalimide structures with some classic donor or accepting groups in their structures, with the aim to maximize the expected interactions with classic nitroaromatic derivatives, and tested them for TNT detection, in this way we arrived to a new naphthalimide dye with optimum features for the selective and ultrasensitive detection of traces of TNT on surfaces and a new material for solvent-free fast detection of TNT on surfaces. In this way, the Fig.…”

AIE/AEE tripodal PEGyl-melphalan supramolecules and detection of trinitrophenol in water

“…Fluorescence-based sensing methods stand out among various techniques due to their simplicity, high sensitivity, affordability, straightforward sample preparation, and portability, offering immense potential. 7 Lots of uorescent sensors have been constructed to detect PA. [8][9][10] A donor-acceptor conjugated polymer based on diethylamine phenyl and benzothiadiazole groups was fabricated to detect PA with a K sv constant of 1.8 × 10 3 M −1 . 11 Hyperbranched conjugated polymers (HCPs) were rst synthesized using truxene and diethynylbenzene derivates, which were carried by F127 in water to form highly uorescent HCP micelles.…”
