Article Preview

A novel ligand with double sulfinyl groups, bis(benzylsulfinyl)methane L, was synthesized by a new method. Its novel ternary complex, has been synthesized [using L as the first ligand, and dipyridyl L' as the second ligand]. In order to study the effect of the second ligand on the fluorescence properties of rare-earth sulfoxide complex, a novel binary europium complex has been synthesized. Photoluminescent measurement showed that the first ligand L could efficiently transfer the energy to Eu (III) ions in the complex. Furthermore, the detailed luminescence analyses on the rare earth complexes indicated that the ternary Eu (III) complex manifested stronger fluorescence intensities, longer lifetimes, and higher fluorescence quantum efficiencies than the binary Eu (III) materials. The fluorescence emission intensities and fluorescence lifetimes of the ternary complex enhanced more obviously than the binary complex.
