We were reported here, the synthesis, characterization, aggregation and electrochemical properties of 4,5-bis(2-{[4-(2- benzyl)phenoxy)benzyl]thio}ethoxy)phthalonitrile and 2,3,9,16, 17,23,24-octa[(2-{[4-(2-benzyl)phenoxy)benzyl]thio}ethoxy)] phthalociyaninatocobalt(II). CoPc were prepared by the reaction of 4,5-bis(2-{[4-(2-benzyl)phenoxy)benzyl]thio}ethoxy) phthalonitrile with the corresponding anhydrous metal salt in n-pentanol and DBU. The structures of the original compounds were identified by using elemental analysis, 1 H-NMR, 13C-NMR, IR, mass and UVvis spectroscopic data. Electrochemical redox characteristics of the compounds were determined by electroanalytical techniques such as cyclic voltammetry, square wave voltammetry. The aggregation tendencies and electrochemical redox properties of all phthalocyanines were investigated on the basis of central metal, solvent medium and substituent effects, using UV-Vis spectral.
