摘要
以2,3,5,6-四氟-1,4-苯二甲醇为原料,经选择性单醚化、溴代及酯化反应合成了一种新型的氟醚链(Ⅰ),通过IR、MS、1H NMR对目标化合物和中间体结构进行了确证。以此作为富π电子供体和缺π电子联吡啶大环化合物环双(百草枯-亚苯基)四阳离子环蕃(CPQT)自组装形成新型准轮烷Ⅱ(I.CPQT),并利用1H NMR化学位移变化跟踪该准轮烷在温度调控下的分子开关功能。
Novel fluorine-containing ether chain （I） was synthesized from 2,3,5,6-tetrafluoro-1,4-benzenedimethanol via selective single etherification, bromination and esterification. The structures of the target compound and its intermediates were determined by IR, MS and ^1H NMR. One new pseudotaxane Ⅱ （I. CPQT） was formed in solution by the self-assembly of electron donor （ I ） with electron accepter eyclobis （ paraquat-phenylene ） tetracationiecyclophane （ CPQT）, and its properties of the reversible molecular switch controlled by temperature-base action was followed by ^1H NMR technique.
