Novel fluorogenic receptor, S1 senses highly toxic cyanide ions with typical fluorescent enhancement via inhibition of TICT process. Bioimaging of RAW264.7 cells and real sample analysis of cyanide ions in the domestic waste water were demonstrated.
The fluorescence sensing properties of a naphthalene-based acetohydrazide (3) were investigated. A highly selective “turn-on” response was obtained towards Al3+ ions, and this was used for real sample analysis and development of paper test strips.
A fluorescent-colorimetric azo dye based bis-Schiff base chemosensor, L, has been developed. L can selectively detect S2− through a color change from yellow to orange in perfect aqueous solution by deprotonation mechanism.
