Summary:The mini-review highlights key structural features and provides guidelines for the molecular design of ambipolar redox-active frameworks, which are of interest for the fabrication of all-organic ‘poleless’ batteries and semiconductors. Open-shell molecules that can form at least three relatively stable redox states (i.e. cationic, neutral, and anionic) are discussed. The efficiency of the suggested strategies is supported by the representative examples taken from the recent publications. [Display omitted] •Ambipolar radicals should contain both donor and acceptor groups.•Donor/acceptor groups with adjustable conjugation facilitate ambipolar behavior.•Intramolecular through-space interactions can stabilize redox states.
