Enhanced conductivity in conjugated polymer blends can be achieved by supramolecular self‐assembly. The authors demonstrate that the morphology of the conducting polymer blend can be modified by crosslinking of one of its components. Ionic crosslinking of the conducting component—poly(3,4‐ethylenedioxythiophene) doped with poly(styrenesulfonate) (PEDOT‐PSS)—is shown to result in a three‐dimensional network and an increase in the electrical conductivity by a few orders of magnitude. For the ionic crosslinking a bivalent cation, such as Mg 2+ , is used.
