Abstract


This synthesized two sulfonated metal phthalocyanine compounds : vanadyl phthalocyanine (VOTsPc) and sulfonated phthalocyanine tin (SnTsPc). Prepared by electrostatic self-assembly technique containing cationic polyelectrolyte and sulfonated metal phthalocyanine alternating composite multilayer film blends . UV - visible spectroscopy track assembly process , the results indicate that the assembly process is uniform , continuous and regular , the film layer is controllable. Using atomic force microscopy (AFM) studies of self -assembled monolayer surface morphology , the results show that the surface of the film tightly filled spherical nanoparticles . Studied by cyclic voltammetry DR / SnTsPc multilayer film modified electrode electrocatalytic reduction of trichloroacetic acid properties. By Z- scan technique for PEI / VOTsPc third-order nonlinear optical properties of the film were tested , the measured nonlinear refractive index γ is membrane 1.2 × 10 -12 m 2 / W, to fit the experimental data and the calculated sample nonlinear absorption coefficient β of 1.02 × 10 -5 m / W, sample third-order nonlinear susceptibility x (3) value of 1.57 × 10 -6 esu.
