Synthesis of phthalocyanines carrying redox active cobalt, titanium, manganese metal center and their electropolymerization properties

The aim of this work is to synthesise, characterise and investigate electrochemical and electropolymerization properties of novel phthalocyanines carrying redox active cobalt, titanium, manganese metal center. 5-{[(1E)-(4-morpholin-4-ylphenyl)methylene]amino}-1-naphthol (1) and 4-[(5-{[(1E)-(4-morpholin-4-ylphenyl)methylene]amino}-1-naphthyl)oxy]phtalonitrile (3) compounds were synthesized by using methods in literature. Starting from (3), peripherally tetrasubstituted metallophthalocyanines 3a, 3b, 3c compounds were synthesized respectively using metal salt CoCl2, Ti(OCH2CH2CH2CH3)4, MnCl2 in the presence of n-penthanol and 1,8-diazabisiklo[5,4,0]undec-7-ene (DBU) at 160oC. That structures of the synthesized compounds were identified by using IR, 1H-NMR, 13C-NMR, UV-vis (only for 3a, 3b, 3c) ve MS spectroscopic data. Electrochemical and electropolymerization properties of the phthalocyanines carrying redox active cobalt, titanium, manganese metal center were investigated by using cyclic voltammetry (CV) and square wave voltammetry (SWV) techniques.
