The present invention provides (polymeric) compounds and a process for preparation thereof. Intended use is in field of electrochemistry. Anion-conducting properties of disclosed compounds making this material suitable for preparing anion-conducting membranes. It is object of present invention to provide an easy-to-prepare material with proper anion-conducting properties and controlled swelling. Inexpensive precursors shall be used for synthesis. This problem has been solved by providing compounds characterized by at least one unit of the formula (I)with X being a structure element comprising at least one nitrogen atom with a positive charge bonded to C1 and C2 and bonded via two bonds to one or two hydrocarbon radical(s) comprising 1 to 12 carbon atoms and Z being a structure element comprising a carbon atom being bonded to C3 and C4 and at least one aromatic 6-ring directly bonded to one of the oxygen atoms, wherein said aromatic 6-ring is substituted in position 3 and 5 with the same or different alkyl group having from 1 to 4 carbon atoms
