In this study, the synthesis of non-ionic and ionic soluble axially disubstituted silicon phthalocyanines has been reported. Aggregation behavior of the silicon phthalocyanines was investigated in different solvents and concentrations. In all studied solvents and concentrations, silicon phthalocyanines were non-aggregated. Electrochemical and electropolymerization properties of the silicon phthalocyanines were studied by cyclic and square wave voltammetry. Electrochemistry of silicon phthalocyanines bearing polymerizable dimethylamino and diethylamino groups were introduced. Silicon phthalocyanines displayed only phthalocyanine ring based reduction redox processes during the cathodic potential scans. However, the silicon phthalocyanine complexes during the anodic potential scans were coated on the working electrode owing to the oxidative electropolymerization of dimethylamino and diethylamino groups on the substituents of the complexes.
