Organic mixed ionic and electronic conductors typically have heterogeneous conjugated macromolecular backbones and ether-based pendant groups to transport ions and charges. Non-conjugated redox active radical polymers that conduct both charge and mass when moving from this archetype to the one with a single component have significant benefits. Here, we use the ionic dopant lithium bis(trifluoromethanesulfonyl)imide salt for long-distance (i.e., length＞ 50 μm) mixed ionic and electron conduction. Using this ionic dopant to tune the exact chemistry of the functional radical pendant group is of key importance in improving long-distance electrical conductivity. Our findings demonstrate a polymer design paradigm that differs significantly from the generally accepted heterogeneous configuration for the generation of next-generation organic mixed ionic and electron conductors.
