The First [2]Pseudorotaxane and the First Pseudocryptand-Type Poly[2]pseudorotaxane Based on Bis(<i>meta</i>-phenylene)-32-Crown-10 and Paraquat Derivatives

By the self-assembly of a bis(meta-phenylene)-32-crown-10 bearing two electron-donating groups (carbazoles) with electron-accepting paraquat derivatives, the first [2]pseudorotaxane and the first pseudocryptand-type poly[2]pseudorotaxane based on bis(meta-phenylene)-32-crown-10 were isolated as crystalline solids as shown by X-ray analyses.
