A simple colorimetric and turn-on fluorescence receptor FT (thiophene appended fluorescein-hydrazone derivative) was prepared and its cation-sensing properties were investigated. Receptor FT displayed a selective colorimetric change (from colorless to orange color) upon binding to Hg in DMSO/HO (1:9, v/v) solution. The association constant of FT-Hg complex was calculated to be 3.03 × 10 M, and the detection limit for Hg was found to be 0.24 ppm.
制备了一种简单的比色和开启型荧光受体FT（噻吩连接的荧光素腙衍生物），并研究了其阳离子传感特性。受体FT在二甲基亚砜/水（1:9，v/v）溶液中与汞结合时显示出选择性比色变化（从无色变为橙色）。FT-Hg络合物的缔合常数经计算为3.03×10⁶ M，汞的检测限为0.24 ppm。
