✦ Synopsis

Non-ionic amphiphilic zinc(II) phthalocyanine 4 with eight oxyethylene side chains exhibits excellent solubility in water and organic solvents such as benzene, chloroform, methanol, THF and DMF. The monomer–aggregate equilibrium of 4 was affected by the solvent polarity. Photoreduction of methylviologen (MV^2+^) in the presence of triethanolamine was also studied with the use of non-ionic complex 4 under light irradiation. The yield for the radical formation of MV^2+^ was greatly increased by the addition of dimethylsulfoxide (DMSO) and cetyltrimethylammonium chloride (CTAC) in aqueous solution.
