Microelectrochemical diode

The redox behavior of PVFc (VFc ) has been utilized in the construction of a microelectrochemical diode along with a redox-active viologen-based V,A -dibenzyl-4,4 -bipyridinium-based polymer (BPQ ). The polymers were coated upon microelectrodes and current was found to pass when the negative lead was attached to the (BPQ ) electrode and the positive lead was connected to the (VFc ) electrode. Thus, as the applied potential approached the difference in redox potentials of the two polymers, current flowed as shown in Equation (5a), and is favorable by p 0.9V. However, current does not flow if the applied potential is in the opposite sense as seen in Equation (5b), as it is disfavored by 0.9 V. The switching time of this diode, which is controlled by the time required to oxidize or reduce the polymers, was long in comparison with that of the solid-state diodes. ... [Pg.303]
