RIVERA, Margarita et al. Electrochemical and Atomic Force Microscopy Investigations of New Materials from N-Trifluoromethanesulfonyl-1-azahexa-1,3,5-trienes Derivatives. J. Mex. Chem. Soc [online]. 2005, vol.49, n.2, pp.78-83. ISSN 1870-249X.

Thin films have been created on the surface of highly oriented pyrolytic graphite electrodes from chemically synthesized π-donor species by using the cyclic voltammetry technique and in situ electrochemistry-atomic force microscopy. Results indicate that it is possible to form new compounds called molecular materials from the coupling of electro-oxidized N-trifluoro-methanesulfonyl-1-azahexa-1,3,5-triene species and a [Cr(C2O4)3]3- anion. Different techniques such as AFM, SEM and EDS were employed to characterize the films morphology and composition. Results indicate that the new materials exhibited a particular electrochemical response and a different film texture depending on the chemical composition of the starting compounds.

Keywords : thin films; electrodeposition; in situ AFM.
