Electrochemical and atomic force microscopy investigations of new materials from N-trifluoromethanesulfonyl-1-azahexa-1,3,5-trienes derivatives

Abstract

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 electrooxidized N- trifluoromethanesulfonyl-1-azahexa-1,3,5-triene species and a [Cr(C 2O4)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. ©2005 Sociedade Brasileira de Química.
