“…Exposure to sodium cyanide at a concentration of 286 mg/m 3 or to hydrogen cyanide at a concentration higher than 300 mg/m 3 for 1 minute may be fatal. Many different methods have been developed for the detection of cyanide anions, including electrochemistry, capillary electrophoresis, fluorometry and chromatography . Unfortunately, most of these methods require sophisticated instruments and involve complicated procedures.…”

“…Many different methods have been developed for the detection of cyanide anions, including electrochemistry, capillary electrophoresis, fluorometry and chromatography. [8][9][10][11] Unfortunately, most of these methods require sophisticated instruments and involve complicated procedures. Therefore, the detection and analysis of cyanide anions by using chemosensors that exhibit optical responses (colorimetric and/ or fluorescence) has attracted increasing attention because of their high sensitivity and simplicity.…”

The sensing properties of dyes based on 2(1H) quinolones containing dicyanoethylene groups towards selected anions such as CN−, F−, I−, Cl−, SCN−, CH3COO−, NO2- and ClO4- were evaluated. The spectroscopic responses of these compounds were investigated in a solution of acetonitrile/water (1:9, v/v) and phosphate buffer at a pH of 7.4. These dyes were found to act as efficient colorimetric and high turn–off fluorescent sensors to cyanide anions. The fluorescence intensity was linearly related to the concentration of CN− from 1 to 10 µmol/L, and the detection limits reached a micromolar level of 6.7, 11.1, 3.8 and 7.2 µmol/L for 1‐4, respectively. The cytotoxic effect of the dyes against human neuroblastoma cells (SH‐SY5Y) was also determined by MTT assay. The examined compounds exhibited slight cytotoxicity against cells under experimental conditions.
