Third‐order nonlinear optical susceptibility, χ (3) of symmetrically octa‐substituted metal‐free phthalocyanine thin films measured by the third‐harmonic generation technique are reported. The metal‐free phthalocyanine has been found to show a χ (3) (−3ω; ω,ω, ω) value as large as 7.73×10 −12 esu at 1.80 μm. The figure of merit, χ (3) /α, was estimated to be 4.17×10 17 esu cm at 1.05 μm and 6.97×10 16 esu cm at 1.65 μm. Both linear and third‐order optical properties of liquid‐crystalline metal‐free phthalocyanines are discussed
