Chemosensor (CS1) was designed and synthesized by simple green chemistry procedure. CS1 exhibited both colorimetric and fluorescence turn-off responses for cyanide (CN(-)) ion in aqueous solution. The probe showed an immediate visible color changes from yellow to colorless and green fluorescence disappearance when CN(-) was added. The mechanism of chemosensor reaction with CN(-) was studied using (1)HH NMR and (13)C NMR spectroscopies and mass spectrometry. Moreover, test strips based on the sensor were fabricated, which served as convenient and efficient CN(-) test kits.
化学传感器（CS1）通过简单的绿色化学程序设计并合成。CS1在水溶液中对氰化物（CN(-)）离子表现出比色和荧光猝灭响应。当加入CN(-)时，该探针立即出现从黄色到无色的明显颜色变化以及绿色荧光消失。使用(1)HH NMR、(13)C NMR光谱和质谱研究了化学传感器与CN(-)反应的机理。此外，还制备了基于该传感器的测试条，其可作为方便且高效的CN(-)测试试剂盒。
