Peripherally tetra-substituted oxo-titanium(IV) phthalocyanines bearing (2-{2-[3-(dimethylamino) phenoxy] ethoxy} ethoxy) and (2-{2-[3-(diethylamino) phenoxy] ethoxy} ethoxy) groups and their cationic derivatives have been synthesized. Electrochemical properties of the complexes 5 and 6 were determined with cyclic voltammetry and square wave voltammetry techniques. Electrochemical studies reveal that metallophthalocyanines containing redox active metal center such as Ti(IV) extends the redox richness of the phthalocyanine ring. Although titanium phthalocyanines complexes give common reduction processes, titanium phthalocyanines electropolymerized on the working electrode during anodic and whole potential scans. Electropolymerization mechanism changes with changing the potential window of the electrolyte system.
