Abstract

A novel Zn2+ 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 1H NMR. The probe gives significant fluorescence enhancement immediately following Zn2+ addition at neutral pH and exhibits improved selectivity for Zn2+ compared to the other metal ions in aqueous solution. The spectra and fluorescence ...
