ABSTRACT: Morphological structure and growth process of LbL nanostructured films from nickel tetrasulfonated phthalocyanine (NiTsPc) alternated with polyallylamine hydrochloride (PAH) were investigated. The experimental results of UV-visible adsorption kinetics (modeled by Johnson-Mehl-Avrami functions) and AFM images analyzes suggested that the surface morphology structure of films is formed by rod-shaped aggregates produced by a two-step growth process: nucleation and diffusion-limited growth.
