Third-order nonlinear optical susceptibility, k3) of symmetrically octa-substituted metalfree phthalocyanine thin films measured by the third-harmonic generation technique are reported. The metal-free hthalocyanine has been found to show a 3) ( -3w; 44 m) value as large as 7 . 7 3 ~ lo-'\* esu at 1.
