Cellulose is functionalized with different monosaccharides by the azide–alkyne click chemistry approach. Either azide or alkyne moieties are attached to the cellulose backbone and allowed to react with sugar moieties bearing the opposite clickable groups. Between 16% and 100% of the reactive sites at the polymer can be functionalized with sugar molecules and a clear correlation between steric demand and DSSugar is observed. The polymers remain soluble in aprotic dipolar media like dimethyl sulfoxide. Products with a sufficient hydrophilicity dissolve in water as well. FTIR- and NMR spectroscopy reveal the triazole formation and indicate an incomplete conversion of the reactive sites as usually observed in the field of click chemistry with polymers.
