Organic radical polymers have unusual electronic properties, with potential applications in batteries, electronics, and memory storage (13). The first nitroxide-based organic radical polymer, reported by Okawara and co-workers in 1972 (4), has since been used as an electroactive material in battery electrodes (5). With recent explorations into organic radical polymers for thermoelectrics and electronics (2, 6), the electrical conductivity of these materials has become a center of interest. On page 1391 of this issue, Joo et al. (7) add an important facet to this discussion by demonstrating the highest reported conductivity for an organic radical polymer.
