摘要：
A benzothiazole derivative linked "off-on" multi-responsive and selective chemosensor 3 has been synthesized and evaluated for cation recognition properties. The receptor 3 shows a high sensitivity and selectivity for Zn2+ through a 'turn-on' fluorescence response over the other tested cations with a detection limit as low as 0.67 mu M. The receptor 3 was successfully applied for the detection of Zn2+ in live HeLa cells. Then, the Zn2+ complex of receptor 3 was also used for cyanide detection and recognition.
