Synthesis, optical spectroscopy and electrochemistry of TTF-derived metallophthalocyanine complexes

Two tetrathiafulvalene (TTF)-derived metallophthalocyanine complexes were synthesized. The structures of the target compounds and their intermediates have been characterized by NMR, MS, EA, UV-VIS and mp. The results of cyclic voltammetry indicated that the presence of zinc or magnesium phthalocyanine slightly affected the first oxidation of 4,5-ethylenedithiotetrathiafulvalene (EDT-TTF) unit. The EDT-TTF unit on the peripheral sites of the zinc phthalocyanine core could be more easily oxidized than the one on the same sites of the magnesium phthalocyanine core.
