我们研制了一种新型的苯并噻唑半花青铜(II)络合物的比色和荧光双模式化学传感器，用于100%水溶液中有毒氰离子的检测。这种双模式响应是通过在氰化物存在下从传感器络合物中去除铜(II)离子以恢复半花菁染料的内部电荷转移(ICT)特性来实现的。该传感器具有良好的灵敏度(μM级检测下限)，在其他常见干扰阴离子存在的情况下，对氰化物具有很高的选择性。
We have developed a new class of benzothiazolium hemicyanine Cu(II) complex based colorimetric and fluorometric dual-modal chemosensor for the toxic cyanide anion in 100% water solution. This dual-modal response was achieved by the removal of Cu(II) ions from sensor complex in the presence of cyanide to recover the internal charge transfer (ICT) character of the hemicyanine dye. The novel sensor shows good sensitivity with μM-level detection limit, and displays high selectivity to cyanide in the presence of other common interference anions.
