Electrochemical Characterization of Two Perylenetetracarboxylic Diimides: Langmuir−Blodgett Films and Carbon Paste Electrodes
dataset
posted on 2004-01-27, 00:00 authored by V. Parra, T. Del Caño, M. L. Rodríguez-Méndez, J. A. de Saja, R. F. ArocaThe cyclic voltammograms (CV) of N,N‘-bis(propyl)-3,4,9,10-perylenebis(dicarboximide)
[PTCDIPr] and N,N‘-bis(neopentyl)-3,4,9,10-perylenebis(dicarboximide)[BNPTCD] in Langmuir−Blodgett (LB) films, in carbon paste electrode (CPE), and in solution for BNPTCD
are reported here for the first time. The data allow a comparison of the electrochemical
behavior of highly organized LB films with the results obtained on CPE, where the active
molecules are randomly dispersed in a carbonaceous matrix. The electrochemical reduction
waves indicate the reversible formation of stable radical anions and dianions. The discussion
of reduction potentials is integrated with spectroscopic data and the HOMO−LUMO energy
positions of both materials obtained from density functional theory computations.
