Abstract

Different techniques of thin film preparation can be applied for substrate modification. This project will explore substrate modification with N,N'-bis(salicylidene)-1,3-propanediamine of nickel(II) (Ni-Salpn) and iro phthalocyanine using the electropolymerization and Langmuir-Schaefer (LS) techniques. The different supramolecular architectures of the thin films may lead to different electrochemical responses. The optical microscopy, scanning electron microscopy, atomic force microscopy, UV-Vis absorption spectroscopy, FTIR, Raman scattering and X-ray diffraction techniques, will be applied for the supramolecular architecture determination of the thin films. Different voltammetric techniques will be used for the electrochemical characterization and catecholamine determination, as L-Dopa and dopamine. The main goal of this project is to contribute to the field related to electrochemical sensors from electrodes modified with thin films that present different supramolecular architectures.
