Supramolecular polymers formed by bifunctional cyclodextrin derivatives

The mixture of monofunctional and bifunctional cyclodextrin derivatives formed branched supramolecular polymers, which showed an increase in the viscosity of aqueous solution. However, a monofunctional cyclodextrin derivative did not form viscous solutions. It is caused by the crosslinking of linear supramolecular polymers through hetero-type inclusion and some intermolecular interactions.
