title: [Synthesis, characterization and fluorescence property of an unsymmetrical Schiff base and its copper complex].
abstract: An unsymmetrical tetradentate Schiff base ligand (H2L) was synthesized using 5-chloro-2-hydroxybenzophenone, o-phenylenediamine and salicylaldehyde. A solid complex of this ligand CuL was prepared and characterized by elemental analyses, IR spectra, UV spectra, TG-DTG and molar conductance. Possible structure of this complex was proposed. The fluorescence property of the ligand and complex was also studied. The result indicates that the Schiff base reagent exhibits a maximum of fluorescence emission spectrum at 385 nm. At pH 9.62, the copper complex of this reagent can cause fluorescence quenching of the reagent.
