Kopsavilkums

Diethylammonium tetrachlorcuprate NH₂(C₂H₅)₂CuCl₄ (DEA-CuCl₄) nanoparticles with sizes about 10 nm were synthesized and embedded into the PMMA polymer matrices. Using DSC temperature study a substantial influence of the polymer matrix on the phase transition temperatures was shown, reflecting a disturbing effect of principal 3d Cu-3p Cl metal-ligand charge transfer bands. Dependence of the absorption spectra on the nanocrystallites (NC) concentration was studied. It was established that an increase of the NC content results in spectral shift of CuCl₄ absorption bands. Explanation of this phenomenon has been suggested within a framework of first principle crystal field quantum chemical calculations.
