摘　　要：以氯代环氧丙烷和氢醌为原料合成了一系列含有丙三醇单元的低聚酚醚链化合物。采用变温核磁共振技术研究了低聚酚醚链与缺π电子联吡啶环蕃CPQT不同比例下在溶液中的自组装行为。结果表明,当酚醚链化合物与CPQT的摩尔比为1∶1时,芳醚链化合物中苯环氢的化学位移值变化有一定的差异;但是当二者的摩尔比达到1∶2或者1∶3时,苯环氢的化学位移值变化趋于平均化。同时,随着温度的升高,CPQT和芳醚链的相对运动速度加快,芳醚链的去屏蔽作用增强,苯环氢的化学位移变化趋于平均化。A series of poly（ hydroquinone ether）s containing propanetriol units were prepared from hydroquinone and epoxy chloropropane in good yields. The oligomers can sell-assemble into a novel pseuaorotaxane with or-electron-deficient bipyridinium cyclophane（CPQT） via π-π stacking interaction and weak interaction. ether chain and CPQT were different. However, the chemical shift changes of different aromatic rings in the 1：2 complex or 1：3 complex formed between ether chain and CPQT were the same. They can become molecular device which may be controlled at a molecular level.
