title: Synthesis and spectral studies of 2-[(N-ethyl carbazole)-3-sulfonyl ethylenediamine]-1-N,N-2-(2-methypyridy) as a fluorescence probe for Zn²⁺.
abstract: 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 the other metal ions in aqueous solution. The spectra and fluorescence quantum yield of the synthesized compound were carefully investigated by UV-vis absorption and fluorescence spectra in various solvents.
