Molecular cages for the selective detection of aromatic nitro compounds

Abstract With the widespread application of aromatic nitro compounds (ANCs) in multiple fields, such as pesticides, pharmaceuticals, high-energy explosives, and industrial dyes, the rapid detection of trace amounts is crucial for environmental safety and human health. In this article, a molecular cage CC7 was synthesized to detect 2,4-DNT based on the fluorescence quenching method, which exhibits high selectivity and sensitivity for 2,4-DNT with a detection limit of 0.53μM, providing a new method for the detection of energetic compounds.
