摘　　要：合成了一种新的阴离子受体,分子结构中同时具有双重结合基团—脲基和氨基及双重变色效应基团—偶氮和硝基,并通过1H NMR对该化合物进行了表征。紫外吸收光谱和荧光发射光谱表明受体分子可选择性识别和传感F-离子,但不具备高的灵敏度。文中并对F-与受体的作用方式进行了探究。A novel anion receptor was synthesized. At the same time, the molecular structure contained dual combination group of urea and amino and double color effect group of azo and nitrocellulose. The compounds were characterization by 1H NMR. Ultraviolet absorption spectra and fluorescence emission spectra showed that the receptor could selectively recognize and sense F- ions, but without high sensitivity. The reaction mechanism of the F- with the receptor was also explored.
