Chloride Lanthanides with Heterocyclic Diimines as Potential Components of Nanocomposite Materials

Two families of lanthanide chlorides with 1,10-phenanthroline or 2,2?-bipyridine were synthesized. Their luminescence properties were investigated in the solid state and 1-dodecyl-3-methylimidazolium chloride solution. Structural peculiarities the of lanthanide chloride complexes were elucidated by joint analysis of the X-ray, vibrational and lifetimes data. As a result the analysis of efficiency of energy transfer processes was performed and the correlation between the structure and the luminescence efficiency has been demonstrated in the systems studied.
