Synthesis of nonperipherally tetra-[5-(diethylamino)-2-formylphenoxy] substituted metallophthalocyanines and their electrochemistry.

3-[5-(diethylamino)-2-formylphenoxy]phthalonitrile ( ), metallophthalocyanines , , and bearing [5-(diethylamino)-2-formylphenoxy] groups at nonperipheral positions were prepared for the first time. These compounds were characterized with IR, NMR (only for ), mass and UV-vis (except ) spectroscopy. Voltammetric characterizations of , , and revealed that while , , and showed characteristic Pc ring and/or metal-based reduction reaction, , , and were coated on the working electrode during the oxidation processes owing to the cationic electropolymerizations of the [5-(diethylamino)-2-formylphenoxy] substituents.
