Abstract Changes in the absorption spectrum due to different gegen‐cations of colored cation‐exchange membranes were found and explained by direct interaction between the gegen‐ion and conjugated double‐bond chains in the matrix of the membranes. The decoloration of these membranes as a result of current transfer through them was determined. Tracer experiments showed that during current transfer, Cl − ions become covalently bound to the matrix of the membrane. A theory for the electronic conductance through conjugated double‐bond chains in ionic environment was developed, in consistency with the experimental results.
