A chemosensor bearing dipyrrolyl motifs as recognition sites and a tetrathiafulvalene redox tag has been evaluated as an optical and redox sensor for a series of anions (F−, Cl−, Br−, HSO4−, CH3COO−, and H2PO4−) in DCM solution. The receptor shows specific optical signaling for fluoride but little electrochemical effect in solution. The solid-state performance of the sensor leads to measurable changes in water. Design implications towards better systems based on these results and other examples are discussed.
研究人员对一种化学传感器进行了评估,该传感器以二吡咯基团为识别位点,并带有四噻吩氧化还原标签,是一种光学和氧化还原传感器,可检测 DCM 溶液中的一系列阴离子(F-、Cl-、Br-、HSO4-、CH3COO- 和 H2PO4-)。该受体对氟化物有特定的光学信号,但在溶液中几乎没有电化学效应。传感器的固态性能可导致水中发生可测量的变化。根据这些结果和其他实例,讨论了设计更好的系统的意义。
