| Abstract: | A novel and simple cyanide chemosensor 2-(naphthalen-1-ylmethylene)malononitrile (L) was designed and synthesized via a green chemistry method in water without using any catalyst. The chemosensor showed an excellent sensitivity and selectivity for CN- in aqueous solution. The detection limit could be as low as 1.6×10-7 mol/L (0.16 μmol/L), which is far lower than the WHO guideline of 1.9 μmol/L cyanide for drink water. |
