Here in, we have designed, synthesized and isolated sensor L, as an exclusive selective turn-on fluorescent chemo sensor for cyanide ion. The acetonitrile solution contains L with tetrabutyl ammonium cyanide, results sudden color change from colorless to yellowish-brown. Chemosensor L produced a strong fluorescence response with an enhancement of very high fluorescence intensity while addition of CN ion and the strength of the chemosensor L towards cyanide binding is found to be 3.9813×10M. In order to use this sensor in practical application, we also prepared a cassette which is fabricated with sensor L and we succeeded to sense cyanide ion.
在此，我们设计、合成并分离出了传感器L，它是一种用于氰离子的专属选择性开启型荧光化学传感器。乙腈溶液中含有L和四丁基氯化铵，会导致颜色突然从无色变为黄褐色。化学传感器L在加入氰离子时产生了强烈的荧光响应，荧光强度大幅增强，并且发现化学传感器L对氰化物结合的强度为3.9813×10M。为了在实际应用中使用这种传感器，我们还制备了一个由传感器L制成的盒式装置，并且成功检测到了氰离子。
