A novel Zn 2+ fluorescence probe, 2-[(N-ethyl carbazole)-3-sulfonyl ethylenediamine]-1-N,N-bis(2-methypyrbidy), was designed and synthesized via simple steps, and its structure was confirmed by IR and 1 H NMR. The probe gives significant fluorescence enhancement immediately following Zn 2+ addition at neutral pH and exhibits improved selectivity for Zn 2+ compared to...
