چکیده
New pyridine based ruthenium complexes with different substituents were synthesized and characterized by Uv-Visible, fluorescence, FTIR NMR spectroscopies. The solvent effects of the compounds on photoluminescence properties have been investigated. exhibit solvatochromic effect in solvents. electrochemical studies performed cyclic voltammetry. HOMO LUMO energy levels are range (-5.51)-(-5.52) eV (-3.04)-(-3.07) eV, respectively. These results indicate that there is no an important side groups properties.
