| description | The supramolecular polypseudorotaxane (3) with π-conjugated polyazomethine is directly
synthesized by the polycondensation of two simple inclusion complexes of β-cyclodextrin/o-tolidine (1)
and β-cyclodextrin/p-phthaldehyde (2) and is comprehensively characterized by NMR, FTIR, circular
dichroism spectra, powder X-ray diffraction, thermogravimetric (TG) and differential thermal analysis
(DTA), scanning electron microscopy (SEM), and scanning tunneling microscopy (STM) both in solution
and in the solid state. The results obtained have revealed linear microstructure of polypseudorotaxane
3 and different photophysical behavior as compared with the π-conjugated polyazomethine backbone (4).
The present investigations prove a simple method for preparing supramolecular polypseudorotaxane by
different complexes, which possess the potential to serve as molecular devices/machines and optical
materials. |
