Chemosensors π–π Stacking of explosive nitro aromatic compounds (NACs) on the surface of fluorescent hosts is the major detection protocol in the literature. However, the concept of molecular recognition to differentiate between NACs based on their structural features has been difficult to implement. In their Full Paper on page 805 ff, Subodh Kumar and co‐workers report a benzimidazolium‐based preorganised tripod for efficient and selective recognition of picric acid through fluorescence quenching. The picrate anion binds in the cavity of the tripod and has a detection limit of 1 nM in water and 137 ag cm −2 on TLC strips.
