设计合成了一种新型的阴离子探针,1-羟基-4-甲基-二苯甲酮对硝基苯酰腙。通过核磁共振谱、质谱和元素分析对其结构进行表征,利用UV-Vis光谱、荧光光谱及1HNMR研究了受体与阴离子如AcO-、H2PO4-、F-、Cl-、Br-和I-的相互作用。结果表明,在不借助任何其他昂贵仪器的情况下,该探针分子在干燥DMSO溶液中能够较好的比色识别F-、H2PO4-和AcO-离子,结合常数表明,该阴离子受体对AcO-具有较高的选择性和荧光响应。最后通过1HNMR滴定进一步研究了1-羟基-4-甲基-二苯甲酮对硝基苯酰腙与阴离子F-的相互作用的本质。
A novel anion probe, 1-hydroxy-4-methyl-benzophenone p-nitrobenzoyl hydrazone was designed and synthesized. Its structure was characterized by 1H-NMR, MS and elemental analysis. The UV-vis spectra, fluorescence spectra and 1HNMR spectra of the acceptors and anions such as AcO-, H2PO4-, F-, Cl-, Br- and I- interaction. The results show that the probe molecules can better colorimetrically identify F-, H2PO4- and AcO- ions in a dry DMSO solution without using any other expensive instrument. The binding constant indicates that the anion acceptor has the effect on the AcO - High selectivity and fluorescence response. Finally, the nature of the interaction between 1-hydroxy-4-methyl-benzophenone p-nitrobenzhydrazone and anionic F- was further studied by 1HNMR titration.
