Photo-sensitized reduction of methyl viologen in the presence of triethanolamine was studied with the use of the phthalocyaninatosilicon(IV) complex which exists as a monomer due to the axial hindrance by two methoxo groups. The yield for the radical formation of methyl viologen was low in water and extremely increased with the increase of dimethylsulfoxide in aqueous solution. This shows that the dimer formation is not a main factor for depression of the photocatalytic reaction.
