Abstract:
We synthesized permethylated maltoheptaose oligosaccharides, whose both ends, untrivially, have been functionalized with supramolecular binders 2-ureido-4[1H]-pyrimidinones (UPy) after single ring-opening of β-cyclodextrin counterpart. In 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), they show lyotropic liquid crystallinity. In the dried state they allow linear saccharide-based supramolecular polymers by UPy-dimerization.
