摘要
The design of a simple and efficient fluorescent probe for detecting hypochlorite (ClO−) is of great importance. Herein, we synthesized the hydroxyl-functionalized UiO-66 (UiO-66-(OH)2) by the solvothermal method and its derivative aluminium ion-modified UiO-66-(OH)2 (Al3+@UiO-66-(OH)2) as two fluorescence probes are used for detecting ClO− in the water. The results showed that UiO-66-(OH)2 has excellent fluorescent response ability for ClO− in water. Aluminium ion-modified UiO-66 (Al3+@UiO-66-(OH)2) displayed its high efficiency for the fluorescence detection of ClO− with a response time of 30 s and extraordinary limit of detection of 1.63 μM in water. Moreover, the sensing of ClO− using easily portable Al3+@UiO-66-(OH)2-coated paper strips is also developed. Furthermore, the plausible fluorescence sensing mechanism of UiO-66-(OH)2 for ClO− in aqueous solution was also discussed.
