Synthesis, Characterization, Photophysical and Electrochemical Properties of Pyridine Based Ruthenium Complexes

Abstract

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

Piridin İçeren Rutenyum Komplekslerinin Sentezi, Karakterizasyonu, Fotofiziksel ve Elektrokimyasal Özellikleri

Abstract

Farklı sübstitüentlere sahip yeni piridin esaslı rutenyum kompleksleri sentezlendi ve Uv-Visible, floresans, FTIR ve NMR spektroskopileri ile karakterize edildi. Sentezlenen bileşiklerin fotolüminesans özellikleri üzerine sübsitüentler ve çözücü etkileri araştırılmıştır. Bileşikler farklı çözücüler içerisinde solvakromatik etki göstermektedir. Bileşiklerin elektrokimyasal çalışmaları döngüsel voltammetri ile gerçekleştirildi. HOMO ve LUMO enerji seviyeleri sırasıyla (-5.51)-(-5.52) eV ve (-3.04-(-3.07) eV aralığındadır. Bu sonuçlar yan grupların elektrokimyasal özellikleri üzerine önemli bir etkisinin olmadığını göstermektedir.
