• Copper ions
• Quick recognition

new diethylamine coumarin Schiffs base chemosensor for cyanide and copper ions with benzothiazole as terminal group has been synthesized with very simple method. Its photophysical properties and recognition properties for cyanide and copper ions have also been examined. The compound is found to be able to recognize cyanide anions based on nucleophilic addition and recognize copper ions based on coordination reaction, all these processes can be completed shortly. The detection limits of the compound for CN- and Cu2+ in acetonitrile are 0.0071 mu M (CN-) and 0.014 mu M (Cu2+), respectively. Its detection selectivity for cyanide and copper ions can be visualized with naked eye in solution and test paper. The color changes from reddish brown to white after the addition of cyanide or copper ions in test paper.
