— Metallophthalocyanines (MPc) and tetrasubstituted magnesium phthalocyanines (MgPcR 4 ) were investigated as sensitizers for the photoreduction of methylviologen (MV 2+ ) under visible light(420–800 nm) irradiation using disodium ethylenediaminetetraacetic acid (Na 2 EDTA) as an electron donor in dimethyl formamide (DMF)‐water mixture. Magnesium phthalocyanine and aluminium phthalocyanine were found to be the most efficient sensitizers among nine MPc's examined (M = 2Li, 2Na, Mg, Ca, Al(Cl), Fe, Ni, Co, and Zn). The following sequence of the efficiency among MgPc and MgPcR 4 's was obtained.
