Abstract Quantum‐chemical AM1 calculations were performed to study the geometries, the electronic structures and the second nonlinear optical properties of phthalocyanine and some asymmetrically substituted phthalocyanines, which include tert ‐butyl, amino, dimethylamino, nitro, fluoro, chloro, bromo, iodo and nitrile substituents. The relationships of the second nonlinear optical coefficients β with dipole moment μ, and β with the energy‐gap differences of frontier orbitals Δ E DA were discussed. Two relationships are regular and all Δ E DA ‐ μ show very good linear relationship.
