含氟低聚乙氧基醚链的合成

The synthesis of fluorine-containing ether chains

通过选择性单醚化反应合成并表征了含氟低聚乙氧基富π电子醚链以强吸电子基团—F作为封堵基团,利用其与缺电子联吡啶大环化合物自组装形成准轮烷,从而为合成在分子水平上具有调控功能的分子振荡元件提供实验和理论依据。

The re-electron rich ether chains were synthesized by mono-selected etherification from hydroquinone and 4-fluorophenol. The F-containing group is regarded as the stopper. The oligomer can be self-assembled to be a novel pseudorotaxane with a π-electren deficient bipyfidinium ring,which can lay a foundation for experimental and theoretical study on the synthesis of molecular oscillation machine that can be controlled at a molecular level.
