氨基富π电子醚链的合成与超分子性能研究

Study on the Synthesis and Supramolecular Properties of π-electron-rich Amino Ether Chain

合成、表征了含氨基的富π电子醚链四甘醇-二(2-氨基-4-苄氧基)苯基醚(5),并与不同的缺π电子联吡啶环蕃CPQT、FCPQT、5FCPQT作用形成了新型准轮烷5.CPQT、5.FCPQT、5.5FCPQT。利用核磁共振技术研究了它们在温度和酸碱调控下的分子开关功能。

Synthesis and characterization of the π-electron-rich amino-containing ether chain of tetraglycol（2-amino-4-benzyloxy）phenyl ether（5）.The novel pseudorotaxanes 5·CPQT,5·FCPQT,5·5FCPQT were formed by the reaction of 5 with different π-electrons-deficient bipyridine cyclophanes CPQT,FCPQT,5FCPQT.The temperature-dependent 1H NMR spectroscopy reveals their switch processes by controlling of the temperature and acid-base.
