Three series of novel water-soluble beta-cyclodextrin-dextran polymers have been prepared by "click" chemistry. The polymers were synthesized from alkyne-modified dextrans (AMDs) onto which mono-6-O-deoxy-monoazido-betaCD (N3betaCD) was grafted by a copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC). The polymers have been characterized by NMR spectroscopy and size exclusion chromatography (SEC). The binding properties have been characterized by isothermal titration calorimetry (ITC) and show excellent accessibility of the betaCDs.
