Abstract
Nitroaromatic compounds (NACs) are the components of explosives that pose a serious hazard to the environment and human health, especially 2,4,6‐trinitrophenol (TNP), which has strong explosibility and good water solubility. An effective supramolecular fluorescent probe for nitroaromatic detection is prepared based on the sulfato‐β‐cyclodextrin (SCD)‐induced molecular aggregation of 9,10‐bis{4‐[2‐(N,N,N‐trimethylammonium)hexyloxy]styrene} anthracene dibromide (AnEA) and subsequent aggregation‐induced emission, which presents high sensitivity particularly toward TNP with a detection limit of 586 ppb in water and 23 ppb on the test paper. Herein, a convenient and effective supramolecular means for nitro‐detection in water is provided.
