| 摘 要： | 在硫酸催化作用下,用前体二醛1[1,3-二(2'-甲酰苯氧基)丙烷]和前体二胺2[N,N'-(2-胺基苯基)-2,6-二甲酰亚胺吡啶]合成了[1+1]席夫碱大环化合物3,进一步还原得到饱和大环4。 用1H NMR、IR、元素分析和质谱等技术手段对大环3和4的组成进行了表征。 采用X射线衍射仪测定了大环3 和4的晶体结构。 用UV-Vis光谱仪对大环3和4与系列阴离子的作用分别进行了考察,结果表明,饱和大环4仅对F-有明显的选择性作用,并测定了该配位反应的配位比和平衡常数,进一步考察了大环3和4对甲醇的吸附性能。

| Abstract: | The [1+1] Schiff base macrocyclic compound 3 was synthesized via the condensation of precursor 1 [1,3-bis(2'-formylphenoxy)propane] and precursor 2 [N,N'-(2-aminophenyl)pyridine-2,6-dicarboxamide] in the presence of sulfuric acid. Macrocycle 3 was reduced to the corresponding saturated macrocycle 4. Their structures were characterized by 1H NMR, IR, MS spectra and elemental analysis. The crystal structures of the two macrocycles were determined by the X-ray diffraction analysis. The study of the reaction of the macrocyclic compound 3 or 4 with a series of anions was performed by UV-Vis absorption spectra technique. The results show that the saturated macrocycle 4 displayed a selective recognition for F- ion, and the stoichiometric ratio and the stability constant of the complex were determined. Furthermore the adsorption abilities of the two macrocycles for methanol were investigated. |
