Abstract

Abstract: The Eu(Ⅲ) complex and new Schiff base ligand of taurine and 2-acetylbenzimidazole were synthesized in methyl alcohol. The structure of the complex was determined as Eu2L3(NO3)3(L=C11H12N3O3S) by chemical and elemental analysis, 1H NMR, IR, mass spectrometry, laser Raman and three-dimension fluorescene spectrometry. The main fluorescence emission of the complex was Eu3+ perturbation ligand to light-emitting, along with the Eu3+ center narrow-band luminescence. When the λex=330.0 nm, the Eu3+ ion narrow-band fluorescence is emitted; when λex=410.0 nm, the Eu3+ produces the 525.0 nm emission band.

Key words: acetylbenzimidazole and Taurine Schiff Base, lanthanide complex, Three-dimensional fluorescence excitation and emission spectra
