butylamino)phenyl]acrylonitrile (BBA) were designed for specific recognition of picric acid (PA), an environmental and biological pollutant. The 1:1 host–guest complexes formed between the chemosensors and PA enhanced fluorescencequenching, thus leading to sensitive and selective detection in aqueous media and the solid phase.

inhibited isomerization of the C=N bond, namely chelation-enhanced fluorescence (CHEF) effect. α-Cyanostilbene-modified Schiff L was designed as a highly selective and sensitive zinc chemosensor. The complexation of L with Zn2+ enhanced the fluorescence intensity. This chemosensor could distinguish clearly Zn2+ from Cd2+, a frequently encountered trouble in the design for the Zn2+ fluorescent probes.

derivative, CDB-DMA12, was designed and synthesized as a supramolecular chemosensor for the detection of sodium houttuyfonate (SH) via aggregation-induced emission enhancement (AIEE), which could efficiently bind with SH, then induce an obvious fluorescence enhancement and visible absorption red-shifting (by the naked eye). Accordingly, a linear relationship was found when plotting the fluorescence intensity
