Asymmetric dye clusters with a single fluorophore (Cy3) and multiple quenchers (4'-methylthioazobenzene-4-carboxylate, methyl red, and 4'-dimethylamino-2-nitroazobenzene-4-carboxylate) were prepared. The dye and one-to-five quenchers were tethered through D-threoninol to opposite strands of a DNA duplex. NMR analysis revealed that the clusters
