Two novel nanoscale supramolecular assemblies have been synthesized from 2,2'-bipyridine-4,4'-dicarboxy-bridged bis(6-O-β-cyclodextrin)s possessing a coordinated copper(II) center threaded on different polymer chain (PPG and PDXL) respectively, and characterized by 1H NMR, 2D NOESY, static light scattering, ESR, powder X-ray diffraction patterns, TG-DTA, STM, and TEM images, displaying two bis(pseudopolyrotaxane)s of length ca. 8-10 nm.
