The spectroscopic and nonlinear optical properties of the positional isomers of metal free 4α-(4-tert-butylphenoxy) phthalocyanine are presented. Second order nonlinear polarizability (β), imaginary hyperpolarizability (Im(γ)) and imaginary susceptibility (Im[χ(3)]) values were determined for the four positional isomers. The measured β values of the four isomers displayed the following trend, C4h (34.0 × 10−5 m MW−1) ＞ D2h (28.8 × 10−5 m MW−1) ＞ C2v (22.8 × 10−5 m MW−1) ＞ Cs (13.7 × 10−5 m MW−1).
