Cathodic reactions in the alkali metal-organic semiconductor systems

Cathodic reduction of organic heterocyclic compounds is investigated. The c ompounds are selected from a series of thiopyrane and thiofulvalene derivat ives with semiconductor conduction (10(-4) to 10(-1) S/cm at 298 K). Conver sions of organic semiconductors during cathodic polarization, accompanied b y a change in electrophysical properties, are studied using the impedance, IR and UV spectroscopies and the X-ray and element analyses. The phenomenon of fast ionic transport in solid products of cathodic reactions is discove red. The ionic component of the conductivity is 10(-5)-10(-2) S/cm at 298 K .
