摘要：
The present invention provides compounds, especially polymeric compounds, a process for preparation thereof and for the use of these compounds. Intended use is in the field of electrochemistry. Anion-conducting properties of disclosed compounds making this material suitable for the preparation of anion-conducting membranes. The object of the present invention is therefore to provide material having an ionic conductivity that is stable over long period of time. This object is solved by compounds containing at least one unit of the formula (I)
wherein X being a ketone or sulfone group, wherein Z being a structure element comprising at least one tertiary carbon atom and at least one aromatic 6-ring directly bonded to one of the oxygen atoms, and wherein Y being a structure element comprising at least one nitrogen atom with a positive charge and Y being bonded to said tertiary carbon atom of Z.
