摘要
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 x 10(-7) mol/L (0.16 mu mol/L), which is far lower than the WHO guideline of 1.9 mu mol/L cyanide for drink water.
