根据受体-信号体耦合法, 设计合成了一个基于吡咯希夫碱衍生物的阴离子探针分子(1,4-二醛基吡咯-2,4-二硝基苯基二腙, 1). 通过核磁共振谱、质谱和元素分析表征其结构|利用荧光光谱, 紫外可见吸收光谱以及1H NMR等手段研究了其与F－, AcO－, , Cl－, Br－, I－等离子的作用. 结果表明: 在不借助任何其它昂贵仪器的情况下, 该探针分子在干燥的DMSO溶液中能够较好地比色检测F－, AcO－和 离子. 此外, F－, AcO－, 等离子的加入使得1的荧光强度在413 nm处发生了明显的增强, 而其它被测的阴离子仅引起1的荧光略微变化, Job法实验得出该探针与阴离子的结合比为1∶1.

An anion probe molecule based on pyrrole derivative as its Schiff base (1,4-dicylaldehydepyrrole-2 ,4 -dinitrophenyl-hydrazone, 1) was designed and synthesized according to the binding site-signaling subunit approach. The compound was characterized by 1H NMR, ESI-MS and elemental analyses. The binding properties of the probe with anions such as F－, AcO－, , Cl－, Br－ and I－ were evaluated by fluorescence, UV-Vis and 1H NMR spectra. The results obtained indicated that the compound 1 was a probe for colorimetric detection of F－, AcO－, , without resorting to any expensive spectroscopic instrumentation. In addition, addition of F－, AcO－, resulted in significant enhancement of the fluorescence of 1 at 413 nm, whereas the other anions tested had little influence on the fluorescence of 1. Job s plot showed the formation of 1/anions complexes of 1∶1 stoichiometry.
