Summary:This mini-review highlights key structural features that should be taken into account when creating ambipolar redox-active closed-shell metal-free molecules. This type of compound is strongly required for the fabrication of all-organic ‘poleless’ batteries and semiconductors. The suggested strategies aimed at stabilization of both oxidized (cationic) and reduced (anionic) redox-states are based on the comprehensive analysis of the most successful structures taken from the recent publications. [Display omitted] •Ambipolar molecules contain at least two donor (D) and two acceptor (A) groups.•Implementation of A–A and D–D conjugations is the second precondition of ambipolarity.•Boron bridges and hydrogen bonds can prevent follow-up chemical steps.
