Synthesis and effect of substituent position, metal type on the electrochemical properties of 3-morpholin-4-ylpropoxy groups substituted cobalt, manganese phthalocyanines

Abstract

In this work, 4- 3-morpholin-4-ylpropoxy phthalonitrile 2, 3- 3-morpholin-4-ylpropoxy phthalonitrile 3, Co II Pc and Mn III Pcs containing 3-morpholin-4-ylpropoxy groups at peripheral and nonperipheral positions were synthesized. Phthalonitrile derivatives 2 and 3 , Co II Pc and Mn III Pcs 2a, 2b, 3a, 3b were characterized by using FT-IR, NMR only for 2 and 3 , mass and UV-Vis except 2 and 3 spectral data techniques. Also, electrochemistry of 3-morpholin-4-ylpropoxy group substituted Co II Pc and Mn III Pcs were inspected by using cyclic voltammetry. Electrochemical studies show that 3-morpholin-4-ylpropoxy group substituted Co II Pc and Mn III Pcs electropolymerized on the Pt working electrode.
