Abstract

original image

Another form of molecular self-assembly—the threading and unthreading of ring-shaped molecules on a polymer chain (represented schematically here) was studied by NMR spectroscopy and followed qualitatively for the formation of polymeric inclusion compounds made up of cyclodextrins and poly-(iminooligomethylene)s. The structures of the polymeric inclusion compounds are proven by their conversion to polyrotaxanes.
