A Cu(2+)-specific colorimetric sensor 1, which is stabilized by an intramolecular hydrogen bonding, was designed and developed. The color of 1 changes from purple to blue on addition of 1.0 muM Cu(2+) in aqueous buffer solution, which can be detected by the naked eye. The analytical detection limit for Cu(2+) by the naked eye is as low as 1.0 muM. The stoichiometry for 1 and Cu(2+) in complex is 2:1 in aqueous solution.
设计并开发了一种由分子内氢键稳定的 Cu(2+) 特异性比色传感器 1。在水溶液中加入 1.0 μM 的 Cu(2+)后，1 的颜色从紫色变为蓝色，肉眼即可检测到。通过肉眼检测 Cu(2+)的分析检测限低至 1.0 μM。在水溶液中，1 与 Cu(2+)形成的配合物的化学计量比为 2:1。
