| 摘 要： | 设计并合成了5种呋喃并[3’,4’:5,6]吡啶并[2,3-c]吡唑受体分子, 利用紫外-可见吸收光谱考察了其与F－, Cl－, Br－, AcO－, 等阴离子的作用. 结果表明该类受体分子与阴离子形成氢键配合物, 导致呋喃并吡啶并吡唑受体的光谱发生变化. 测定了配合物的结合比和稳定常数, 发现受体化合物对F－, AcO－离子具有良好的选择性, 对其它多种阴离子无影响. Job曲线表明受体分子与阴离子间形成1∶1型的配合物. |
| 关 键 词： | 呋喃并[3’,4’:5,6]吡啶并[2,3-c]吡唑 阴离子识别 氢键作用 |

| Abstract: | Five new receptors containing furo[3’,4’:5,6]pyrido[2,3-c]pyrazole core were synthesized. The properties of the receptors with anions such as F－, Cl－, Br－, AcO－, and were examined by UV-Vis spectroscopy. The results showed that the receptors have good selectivity to F－ and AcO－. However, no obvious changes were observed on the other anions. The Job plot indicated that a 1∶1 stoichiometry complex was formed between the receptors and anions. The results also showed hydrogen-bonding interaction was formed between the receptors and anions. |
| Keywords: | furo[3' 4':5 6]pyrido[2 3-c]pyrazole anion recognition hydrogen-bonding interaction |
