Three structurally simple thiourea derivatives 1-3 were prepared, and their chromogenic behaviors toward various anions were investigated in aqueous solution. Among them 1 showed good sensitivity and selectivity for cyanide ion and also can distinguish it from other anions by different color changes. Besides that, the receptor 1 has a sensitive detection limit (1.27 μM) for cyanide ion accordingly it can be used as a colorimetric sensor for the determination of cyanide ion. The use of the test strip of sensor 1 to detect cyanide ion was also reported.
合成了 3 种结构简单的硫脲衍生物 1-3，并研究了它们在水溶液中对各种阴离子的显色行为。其中 1 对氰离子表现出良好的灵敏度和选择性，并且可以通过不同的颜色变化将其与其他阴离子区分开来。此外，受体 1 对氰离子具有敏感的检测限（1.27 μM），因此可以用作氰离子的比色传感器。还报道了使用传感器 1 的试纸条来检测氰离子。
