A self‐assembly process with no external template and no added acidic dopant is reported as a method providing quantitative control over the diameter d of the polyaniline (PANI) nanofibers produced. An experimental formula relating d to the standard redox potential of the oxidants is established. The PANI nanofibers in the figure have d ≈ 15 nm.
