二萘嵌苯桥联双二苯并24冠8的合成及其与富勒烯二级铵盐的组装行为

Synthesis of perylene-bridged bis(dibenzo-24-crown-8) and its assembly behavior with a fullerene-based secondary dibenzylammonium salt

通过端基为伯胺的臂式二苯并24冠8与苝四甲酸二酐衍生物的缩合反应合成了二萘嵌苯桥联的双冠醚主体.利用核磁、荧光等手段研究了其与富勒烯二级铵盐客体形成准轮烷的组装行为.结果表明,24冠8大环可以键合二级铵盐客体,形成轮上有二萘嵌苯和轴上有富勒烯的准轮烷,KPF6和18冠6的加入可以调控准轮烷的解离和形成,并伴随着荧光强度的改变.

This paper reports the synthesis of perylene-bridged bis（crown ether） through condensation reaction between primary amine-armed dibenzo-24-crown-8 and 3,4,9,10-perylenetetracarboxylic dianhydride.Pseudorotaxane with an perylene moiety at the wheel and a fullerene unit in the middle of the axle was prepared,which was evidenced by 1H NMR and fluorescence experiments.Those results show that,the addition of KPF6 and 18C6 can adjust the formation and deformation of pseudorotaxane,following the change of the florescence intensity of perylene.
