Voltametric and coulometric methods have been used to study the electroanal
ytical behaviour of 3,8-difluorobenzo[c]cinnoline. The number of electrons
transferred, the wave characteristics, diffusion coefficient and reversibil
ity of the reactions have been investigated in ethyl alcohol-BR. Adsorption
of the molecule on the surface of the mercury drop electrode was analyzed
and this phenomena was exploited to calculate the diffusion coefficient of
3,8-difluorobenzo[c]cinnoline. A mechanism for the electrode reaction was p
roposed. (C) 2001 Elsevier Science B.V. All rights reserved.
