“…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.…”
