A new aromatic hydrazone based on pyrene-1-aldehyde was synthesized and characterized by (1)H NMR and mass spectrometric analyses. The sensing properties of the hydrazone were studied by absorption and fluorescence studies in the aprotic solvent DMSO. It was capable of visual and fluorescent detection of fluoride over competitive ions (Cl(-), Br(-), H2PO4 (-), AcO(-)). Moreover, the in-situ prepared iron(III) complex of the hydrazone was investigated as a turn off fluorescent fluoride sensor in aqueous medium by displacement mechanism.
合成了一种基于芘-1-醛的新型芳香腙，并通过¹H NMR和质谱分析对其进行了表征。在非质子溶剂二甲基亚砜中，通过吸收和荧光研究考察了该腙的传感性能。它能够对氟化物进行可视化和荧光检测，以区分竞争性离子（Cl⁻、Br⁻、H₂PO₄⁻、AcO⁻）。此外，通过置换机理，研究了原位制备的该腙的铁（III）配合物作为水介质中关闭型荧光氟化物传感器的性能。
