“…To date, the fluorescent monomers for the synthesis of ODFs were mainly obtained by nucleophilic substitution of Hoffer’s chlorosugar 23 with different metallated aromatic dyes. 24 In that strategy, the fluorophores are directly attached to the anomeric carbon atom of the sugar. However, major drawbacks of that approach are the relatively low coupling yields, 25 the limited functional group compatibility, and the generation of mixtures of α- and β-anomers, which in some cases can be difficult to separate.…”
