The fluorescence response of a set of cyclam‐triazole‐dye ligands is controlled by the appended dye, but simple reversal of the triazole topology affords a novel probe for Zn 2+ with a longer fluorescence lifetime and higher fluorescence quantum yield upon Zn 2+ binding (< τ > = 2.0 ns, Φ f = 0.76).
