Synthesis and electrochemical and spectroelectrochemical characterization of chloromanganese(III) phthalocyanines

The synthesis of novel, symmetrical, tetrasubstituted manganese phthalocyanine complexes bearing 4 hexylthio, 2’,3’,4’,5’,6’-pentafluorobenzyloxy, 2’,3’,5’,6’-tetrafluoro-4’-hexylthio-benzyloxy, and 2’,3’,5’,6’-tetrafluoro-4’- pentoxy-benzyloxy units is reported. The new compounds have been characterized by using elemental analyses and UV-Vis, FT-IR, and mass spectroscopic data. The electrochemical properties of the manganese phthalocyanine com- plexes were investigated by cyclic and square wave voltammetry and the nature of the observed redox processes was studied by spectroelectrochemistry.
