Özet

This paper describes the preparation and electrochemical properties of novel non-aggregated axially disubstituted silicon phthalocyanine complexes and their water soluble derivatives. Silicon phthalocyanine complexes were highly soluble in common organic solvents (CHCl3, CH2Cl2, DMF, DMSO, THF and EtOAc) and their quaternized derivatives were soluble in DMF, DMSO, EtOH, water. The effect of solvents on absorption spectra were studied in various organic solvents. All silicon phthalocyanine complexes were non-aggregated in common organic solvents. The electrochemistry of silicon phthalocyanine complexes was also studied by cyclic voltammetry (CV) and square wave voltammetry (SWV) methods. Cyclic voltammetry revealed two reversible Pc ring-based one-electron reduction couples and two quasi-reversible Pc ring-based one-electron oxidation couples for complexes 3 and 5.
