摘要： 利用π-π堆积作用,富电子4,4-二氨基二苯醚(A)和4,4-二羟基二苯醚(B)分别与缺电子联吡啶大环(CPQT)自组装成准轮烷A-CPQT和B-CPQT;利用酸碱调控准轮烷A-CPQT的“开”与“关”,此过程可利用体系的核磁共振氢谱的化学位移变化进行跟踪.

Abstract: Anew type pseudorotaxanes are formed in solution by self-assembly of wire-type electron donor 4,4'-oxydianiline(A) and electron accepter cyclo bis(paraquat-phenylene)tetracationic cyclophane(CPQT) which can be unthreaded and rethreaded by acid-base. The threading/unthreading processes are accompanied and therefore can be monitored by strong changes in 1H NMRchemical shift data of system.

Key words: Pseudorotaxane, NMR spectroscopy, Supramolecular, Biphenyl ether
