Abstract: A new Schiff base N, N-bis (furan-2-yl) methylene) butane-1, 4-diamine (L) synthesized by the condensation of Furan-2-carboxaldehyde with benzene-1,2-diamine. The optical response of the compound L towards different metal ions is remarkable both colorimetric and fluorimertic response for Pb2+ ion only. The UV-Vis and fluorescence spectral studies of L with various metal ions were consistent of visual naked eye observation and stoichiometry high binding ability for new fluorescent probes for the detection of Pb (II) metal ions.
