In recent decades, interest in the coordination compounds of lanthanides has been exponential. This is due to both fundamental and applied aspects. The first is related to the relationship between the composition, structure, properties and structural features, and the second - with the use of luminescent coordination compounds as precursors of electroluminescent materials in organic light emitting diodes [1], liquid crystal displays, sensors, molecular thermometers, luminescent labels in biology and analytical chemistry [2].
The β-diketonate complexes of Sm(III) (SmL3.2H2O), heteroligand complexes with phenanthroline  (SmL3.Phen) where L = 2,7-dimethyl-octene-1-3,5-dione, 2,6-dimethyl-heptene-1-3,5-dione, polymers and copolymers with styrene and methyl methacrylate based thereon were synthesized. The complexes were fully characterized using FTIR and thermal analyses. Absorption, diffuse reflectance and emission spectra for the complexes were recorded. The relationship between complex structure and the intensity of fluorescence emission was established. 
It was established that all complexes are able to show effective luminescence.
