摘要：

Conjugated polypseudorotaxane polypyrrole/-cyclodextrin (PPy/-CD) was synthesized by chemical oxidative polymerization of pyrrole in the presence of -CD. The FT-IR spectra and wide-angle X-ray diffraction (WAXD) pattern showed that the pyrrole-CD (Py-CD) rotaxanes were presented in the polypyrrole (PPy) chains. The polypseudorotaxane wires composed of -CD as the insulating cover and polypyrrole as the core were expected product in this study. The elemental analysis suggests that the molar ratio of -CD to pyrrole is 1:5. Because of the discontinuous presence of Py-CD rotaxanes, the conductive behavior morphology and thermal stability of the polypseudorotaxanes are greatly different than those of the pure PPy. Moreover, this work analyzed the reaction mechanism in the microscopic view.
