The synthesis of new fluorescent 2,1,3-benzothiadiazole-triazole-linked glycoconjugates is described by a straightforward synthetic route, using a copper(I)-catalyzed azide–alkyne 1,3-dipolar cycloaddition (CuAAC). UV–visible (UV–vis) and steady-state fluorescence in solution were applied in order t...
