Abstract

The problem addressed was that of providing novel polymers which are preparable with a low level of complexity, with the possibility of controlled influence on the physicochemical properties thereof within wide limits in the course of synthesis, and which are usable as active media in electrical charge storage elements for high storage capacity, long lifetime and stable charging/discharging plateaus.9,10-Bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene polymers consisting of an oligomeric or polymeric compound of the general formula I have been found.
