• Tetrakis (8-quinolineoxy-5-sulfonic acid)-phthalocyanine copper was synthesized.
• The homogeneous film of phthalocyanine copper was fabricated.
• The third-order NLO properties of the film were measured using 4f coherent system.
• The film exhibited excellent nonlinear absorption and self-focusing effect.
• We report a promising third order NLO materials.
Composite film with alternating layers containing anionic 1,8,15,22-tetrakis (8-quinolineoxy-5-sulfonic acid)-phthalocyanine copper and cationic polydiallydimethylammonium chloride was fabricated by electrostatic self-assembled layer-by-layer (LBL) technique. The microstructure of the film was characterized by a series of techniques. The third-order nonlinear optical properties of the film were measured using 4f coherent imaging system with phase object (NIT-PO) with laser duration of 20 ps at the wavelength of 532 nm. The film exhibited excellent nonlinear absorption and self-focusing effect. The second-order molecular hyperpolarizability γ value of the film reaches as high as 1.54 × 10−29 esu.
