Abstract
Abstract— Metallophthalocyanines (MPc) and tetrasubstituted magnesium phthalocyanines (MgPcR4) were investigated as sensitizers for the photoreduction of methylviologen (MV2+) under visible light(420–800 nm) irradiation using disodium ethylenediaminetetraacetic acid (Na2EDTA) 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 MgPcR4's was obtained.
