Abstract

Seven novel polycyclic pyrazoline and pyrazole sensors were synthesised and screened for useful photophysical properties with pyrazoline 2 and pyrazole 7, displaying an Fe "turn-off" response in aqueous environments with Fe limits of detection (LoD) of 2.12 μM and 3.41 μM, respectively. Both 2 and 7 sensors functioned in aqueous environments with real-world examples of Fe detection in tap water and mineral water samples. 2 and 7 are suitable for the detection of Fe at concentrations below the maximum iron limits for drinking water set by the Environmental Protection Agency (EPA) and European Union (EU).

摘要

合成了七种新型多环吡唑啉和吡唑传感器，并与吡唑啉2和吡唑7一起筛选其有用的光物理性质，它们在水性环境中对铁呈现“关闭”响应，铁的检测限（LoD）分别为2.12 μM和3.41 μM。2和7这两种传感器在水性环境中均能发挥作用，并给出了在自来水和矿泉水样品中检测铁的实际示例。2和7适用于检测浓度低于美国环境保护局（EPA）和欧盟（EU）设定的饮用水中铁最大限量的铁。
