... Elsewhere, as is shown in this figure, we note a decreasing of the conductivity on going from PVARu(Terpy)Cl3 to the PVC-Ru(Terpy)Cl3. The decreasing conductivity is probably due to some phenomenon such as intermolecular relaxation induced by application of electric field. This phenomenon favours a ...
