Özet

This paper describes the synthesis, characterization, aggregation and electrochemical behavior of new silicon phthalocyanines with 6-({(1E)-[4-(diethylamino)phenyl]methylene}amino)hexan, 2-[2-({(1E)-[4(diethylamino)phenyl]methylene}amino)ethoxy], 6-({(1E)-[4-(dimethylamino)phenyl]methylene}amino)hexan groups as axial ligands. The aggregation behavior of these complexes was examined at different concentration and solvents. In all studied organic solvents, silicon phthalocyanine complexes were non-aggregated. Electrochemical properties of silicon phthalocyanine complexes 3, 5 and 7 were determined by cyclic and square wave voltammetry. Voltammetric studies reveal that while complex 3 showed two reduction and two oxidation couples, complex 5 showed three reduction and one oxidation couples, on the other hand, complex 7 showed two reduction couples and one oxidation couples.
