Synthesis and Electrochemical Properties of Phthalocyanines Bearing Fc(CH2)ns- and Dodecyl Substituents in Non-Peripheral Positions
Here we present the synthesis of above compounds and the results of their electrochemical investigation. Our particular interest lies in the dependence of ferrocenyl redox properties on the electron withdrawing properties of phthalonitrile. It was found to be a function of the linker atom (S) or lack of thereof as well as the chain length (expressed as n above). The redox properties were probed utilising glassy carbon working electrode as well as gold electrode to immobilize sulphide species. Dodecyl chains attached to the core of macrocycle proved increasing solubility of compounds in organic solvents2 and also led to liquid crystalline properties.
