A new highly sensitive luminescent iridium(III) chemosensor, , was designed and synthesized for tandem detection of fluoride ions (F) and aluminum ions (Al). This sensor exhibited obvious luminesce quenching by hydrogen bond interactions with F. In addition, the resulting complex can be further used to detect Al through a luminesce enhancement. The detection limit (0.02 μM) of for Al is far lower than the World Health Organization (7.41 μM) limit for drinking water. Importantly, chemosensor could be used to detect and quantify F and Al reversibly. This sensor achieved rapid detection of two ions, which relies on only one probe.
一种新型高灵敏度发光铱（III）化学传感器被设计并合成出来，用于串联检测氟离子（F⁻）和铝离子（Al³⁺）。该传感器通过与F⁻形成氢键相互作用表现出明显的荧光猝灭。此外，生成的配合物可进一步用于通过荧光增强来检测Al³⁺。该化学传感器对Al³⁺的检测限（0.02 μM）远低于世界卫生组织规定的饮用水铝含量限值（7.41 μM）。重要的是，化学传感器能够可逆地检测和定量F⁻和Al³⁺。该传感器仅依靠一个探针就能实现对两种离子的快速检测。
