A series of poly (hydroquinone ether)s containing propanetriol units were prepared from hydroquinone and epoxy chloropropane in good yields.The oligomers can self-assemble into a novel pseudorotaxane with π-electron-deficient bipyridinium cyclophane (CPQT) via π-π stacking interaction and weak interaction.The partial temperature-dependent 1H NMR spectra of pseudorotaxane between poly (hydroquinone ether) and CPQT showed that the chemical shift changes of different aromatic rings in the 1:1 complex formed between 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.
