The effect of the solvent polarity on nonlinear optical properties of selected phthalocyanines complexes of copper, cobalt, zinc and magnesium using degenerate four wave mixing (DFWM) method is presented. Ethanol and dimethyl sulfoxide were used as solvents for all studied complexes. The solvent effect is observed for the absorption spectra of metal phthalocyanines (MPcs) solutions. It was noticed that the solvent polarity as well as the central metal ion play a crucial role in determining the values of the second order hyperpolarizability ((eff)) of studied macrocyclic compounds. In general, (eff) values of MPcs solutions are changing with change of the solvent polarity in order of ZnPc > MgPc > CuPc > CoPc. And these values are higher for samples dissolved in polar aprotic solvent than in polar protic solvent.
