| Aryloxyacetyl Hydrazone Receptors: Synthesis and Anion Recognition Properties |

| 摘要: 本文设计合成了3种新型的酰腙类受体分子。利用紫外-可见吸收光谱及 1H NMR考察了其与F-、Cl-、Br-、I-、CH3COO-、HSO4-、NO3-等阴离子的作用。结果表明，该类受体分子能较好地识别阴离子F-和CH3COO-，在DMSO溶液中主客体之间形成氢键加合物。尤其对于受体3(间苯双对硝基苯氧乙酰腙)，加入F-和CH3COO-时，溶液颜色有明显变化，受体3对这两种阴离子可实现裸眼识别。 |

| Abstract: The synthesis, UV-Vis and 1H NMR studies of aryloxyacetyl hydrazone colorimetric sensors for anions are presented. These sensors can recognize anions through hydrogen binding even in competitive DMSO solutions, especially, the receptor 3 (1,3-benzyldi(p-nitro-methylphenyloxy)acetylhydrazone) gives rise to large color change that are clearly visible to the naked eye at the presence of F- and CH3COO-. The results indicate that receptors 1, 2 and 3 complex with anions such as F-, CH3COO- by multiple hydrogen bonding interactions. |
