利用核磁共振研究准轮烷的振荡行为

摘要

Two new type pseudorotaxanes are formed by novel (-electron-rich aromatic polyethers containing hydroxy and thiohydroxy with cyclobis(paraquat-phenylene)tetracationic cyclophane(CPQT) respectively. We use 1H NMR spectroscopy to study the property of pseudorotaxanes, and found that the pseudorotaxane containing hydroxy is more stable than the pseudorotaxane containing thiohydoxy as a result of ［C-H…OH］ hydrogen bonds. Otherwise, we can monitor the pseudorotaxane containing thiohydoxy by Ag+.%利用含巯基苯醚链和含羟基苯醚链分别与缺电子联吡啶大环化合物CPQT形成准轮烷，并利用变温核磁共振技术研究了准轮烷的振荡行为.
