Azacrown-attached meta-ethynylpyridine polymer: saccharide recognition regulated by supramolecular device.
Polymeric synthetic host , azacrown-attached 2,6-pyridylene ethynylene polymer, was investigated for its saccharide recognition and the additive effect of triethylene tetramine-trifluoroacetic acid; heteroallosteric effects were observed on the basis of CD and UV/Vis analyses, which indicated saccharide-dependent stabilization and destabilization of helical complexes by the formation of pseudopolyrotaxanes.
