Electron Transfer Processes at Organic Insulator Electrodes

Electron Transfer Processes at Organic Insulator Electrodes 

The first experiments with anthracene electrodes were performed by Kallmann and Pope. More detailed investigations were performed by Mehl and co-workers (see Ref. 97 and literature cited there). These authors analyzed quantitatively various charge transfer processes. They observed, for instance, a cathodic limiting current for anthracene using as a redox 

Unfortunately, these crystals are not completely inert. Injected charge carriers at the surface, especially holes, undergo slow side reactions which lead to a change of the chemical nature of the crystal surface. This effect has a remarkable influence on the interface-controlled limiting current, as shown by Willig et These authors developed a kind of pulse technique
