A Turn-On Fluorescent Chemosensor for Cyanide Ion Detection in Real Water Samples.

ABSTRACT: We have designed and synthesized a novel simple colorimetric fluorescent probe with aggregation-induced emission (AIE) properties. Probe 5-(4-(diphenylamine)phenyl) thiophen-2-formaldehyde W exhibited a turn-on fluorescent response to cyanide ion (CN^-), which induces distinct visual color changes. Probe W exhibited a highly selective and sensitive ratiometric fluorescence response for the detection of CN^- over a wide pH range (4-11) and in the presence of common interferents. The linear detection of CN^- over the concentration range of 4.00-38.00 µM (R ² = 0.9916, RSD = 0.02) was monitored by UV-Vis absorption spectrometry (UV-Vis) with the limit of detection determined to be 0.48 µM. The linear detection of CN^- ove
