“…In the eld of NAC detection, the applied metal organic frameworks or quantum dots mostly contain cadmium and the pyrene class of sensors are limited by their toxicity. 18,21,25,26 Among the available sensors for picric acid, detection by quenching of the uorescence 18,[27][28][29][30][31] is more explored than 'no quenching uorescence sensors'. [32][33][34][35][36] Currently p-terphenyl benzimidazolium-based molecular baskets, 37 zinc-phthalocyanine framework based chemosensors with uorescence quenching, 38,39 electron-rich triphenylaminebased sensors with charge-transfer complex formation, 40 electrogenerated thin lms of a microporous polymer network responding to NACs, 41 a glucopyranosyl-1,4-dihydropyridine chemosensor, 42 a metal-organic framework [Cd 3 (TPT) 2 -(DMF) 2 ]$(H 2 O) 0.5 for NAC detection, 43 and a self-assembled nanoscopic organic cage for PA detection 44 are some strategies focusing on NAC explosives detection.…”
