Abstract

The aim of this work was to learn how the influence of various solvents correlates with nonlinear optical properties of metallophthalocyanines (MPcs). The method, which was used to measure nonlinear optical properties, was degenerate four wave mixing (DFWM). We used ethanol, chloroform and dimethyl sulfoxide as solvent of metallophthalocyanines. The absorption spectra of MPcs solutions present a narrow Q-band in the visible region and a relatively wide B-band in the near ultraviolet. In all cases we observed the solvatochromism effect. Nonlinear optical properties of MPcs solutions change with using different polarity of solvent in the following way: n₂ _(ZnPc) < n₂ _(CoPc) < n₂ _(CuPc).
