INVESTIGATION OF NEW POLYMER COMPLEXES BASED ON Yb(III) ?-DIKETONATES

The metal polymers based on mono- and heteroligand ?-diketonate complexes of Yb(III) with 2,7-dimethyl-octen-1-dione-3,5, 2,6-dimethyl-heptene-1-dione-3, 5 phenanthroline was synthesized. It has been defined that the coordination environment central ion remains unchanged during radical polymerization. shape position bands in electronic absorption spectra are similar to corresponding monomeric complexes, slight shifts indicate deformation elementary unit polymer formation chain. is shown polymerization process lead an increasing thermal stability comparison analogues. An increase emission established by method luminescent spectroscopy, which due energy, steric, structural-mechanical factors.
