Abstract

Disclosed is an oligomeric or polymeric compound comprising at least two structural units of formula (I) wherein Ar is a carbocyclic aromatic radical or a heterocyclic aromatic radical with the two carbonyl carbon atoms being attached to two ring carbon atoms of the Ar group forming together with the imide-nitrogen atom a five-membered or a six-membered ring X is a divalent group selected from —CR1R2—, —CO—, —SiR3R4—, —P(O)R5—, —P(O)(OR6)—, —PR7—, —P(OR8)—, —S(O)— or —S(O)2—. R1 to R8 independently of one another are hydrogen, alkyl, cycloalkyl, aryl or heteroaryl groups, R9 is a divalent hydrocarbon group or a covalent bond, and R10, R11 and R12 independently of one another are hydrogen or C1-C6 alkyl or R10 and R11 or R10 and R12 together with the carbon atoms to which they are attached form a cycloaliphatic ring or a bicyclic aliphatic system The oligomeric or polymeric compound comprising units of formula (I) of the invention can be used as redox-active material in storage means for electric energy, for example in batteries, redox-flow cells, fuel cells or capacitors.
